As mentioned previously in previous Forgotten Chicago articles there were a total of 13 Shoreline Motels built in Chicago in the roughly ten year period from the mid-1950s to the mid-1960s. In this, the final article in the series, we examine the four Shoreline Motels constructed in Hyde Park and the South Shore areas.

As with Chicago’s other lakefront neighborhoods, the long history of transient accommodations in the neighborhoods south of the Loop spans the 1800s until today. One of the most venerable hotels south of the Loop was the Shoreland Hotel, built in 1926 and remodeled in the 1930s to keep current in a challenging economy by the highly accomplished but now forgotten architect James Eppenstein.

These three Shoreland Hotel promotional items from (left to right) 1930, 1951 and 1954 show how the Shoreland, along with many aging lakefront hotels, attempted to keep current with changing times. At left, it may be deduced that the Shoreland was struggling during the Great Depression from this awkwardly written ad appealing to a budget-conscious renter. At center, the hotel’s ornate 1920s architecture is cleaned up in a 1951 Yellow Pages ad to look as modern as a new Mies van der Rohe skyscraper.

Above right, a new Chevrolet Corvette is prominently placed at the entrance to this elaborate, and very old-fashioned, Roaring Twenties-era hotel. With new highways being built in the Chicago area and a booming economy, there was strong demand starting in the 1950s for new accommodations to supplement and replace Chicago’s aging hotels along the lakefront.


Architectural Forum, 1937

James Eppenstein’s 1930s transformation of the Shoreland Hotel, and many of his other remarkable and now-forgotten projects, will be examined in an upcoming Forgotten Chicago article. Currently being converted into apartments by Studio Gang, it is not known how many of Eppenstein’s original details will be restored.

The Shoreline Motels on the South Side of Chicago followed a similar pattern of development, success, decline and demolition (for three of the four built projects) as most of their other motel counterparts near Lake Michigan. Worth noting is that unlike any of the motels built further north, two of these four South Side motels were demolished for public use — one for a school, and one for an extension of an existing lakefront park.

One of only two Shoreline Motels still in operation as a motel in 2013, the former 50th on the Lake (later TraveLodge, then Hilton Hyde Park, now Ramada Chicago Lakeshore Hotel) opened by Fall, 1958. This property was also by far the largest of the Shoreline Motels built, with more rooms (301 at opening) than the 11-story former Lake Tower Motel (250 rooms) discussed in a previous article.

By the time this motel opened, its name and number of rooms had changed to 301 according to the information in the article pictured above left. Above right is a whimsical 50th on the Lake ashtray, perhaps swiped by a guest as a souvenir and sold decades later. Note how this locally owned motel had no apparent visual consistency in signage, marketing material, or in-room items. The 50th on the Lake also once had a colorful lobby with striking lamps and what may be a homemade check-in desk.

Two of the four Shoreline Motels built on the South Side were announced at the same time, in March 1956.1 These two would open as the 50th on the Lake and the Thunderbird, and were developed by the same team that built Chicago’s first motel, the Sands in the Edgewater neighborhood that opened in December 1955. The postcard above right is taken from author James Lileks; his colorful description of the scene above may be read on his extensive, and hilarious, web site.

As with many of the Shoreline Motels in Chicago, the design of the 50th on the Lake has nothing to do with the often-dense development along Chicago’s lakefront; just to the south of this motel is a still-extant and concentrated district of luxury high-rise apartment buildings dating mostly to the 1920s. Many features of this motel as built have since been changed, including the wall-to-wall windows in guest rooms, and the removal of fish ornaments on the second floor.

Perhaps too expensive to remove at the time of its conversion to a TraveLodge, the original neon “50th on the Lake” signage is still visible in the postcard above. Chicago’s largest Shoreline Motel continues to operate in 2013, and according to the hotel’s web site, this property now has 195 rooms and suites.

Above right, a contemporary view of the Ramada Chicago Lakeshore Hotel shows some of the nearby buildings facing Lake Michigan, many built in the boom years of 1920s and typical of dense urban lakefront buildings in Chicago. According to renderings and contemporary aerial views, the four-story building seen above right was not part of this motel at opening; it appears by 1972 aerial views.2


Epstein

Unlike some other Shoreline Motels, the design of the Shore Drive was strictly business, with a modest neon sign, subdued colors, and decidedly no sun-and-surf theme. The Shore Drive also featured wood paneling on the exterior, unusual for a 1950s Chicago commercial building.


Chuckman Collection, no date

One of the most intriguing of all Chicago motels was the Shore Drive, located just north of the Museum of Science and Industry, on the northwest corner of South Shore Drive at East 56th Street. The second completed Shoreline Motel (opened in April, 1956), it was designed by A. Epstein & Sons (now Epstein) and was the only Shoreline Motel designed by an architecture firm that is not only still thriving in 2013, but one with a large staff and offices outside of the United States.3 Epstein’s work is a longtime favorite of Forgotten Chicago, and the Shore Drive Motel is a typical example of their great skill and expertise in a modest project on a small lot at a high-profile location.

The Shore Drive’s unique underground parking garage is seen above. An old fashioned streetlight is visible in the top image at left, along with dense neighboring buildings more typical along Hyde Park’s lakefront.

Curiously, more photographs, postcards and ephemera have been found for the Shore Drive than for the other three Shoreline Motels on the South Side combined. The postcard above left illustrates how Epstein included underground parking for the Shore Drive — the only known instance of below-grade parking for a Shoreline Motel. The image above right shows Mortons Surf Club, a high-profile (and relatively short-lived) restaurant tenant at the Shore Drive.


Coutesy of Epstein

The Shore Drive’s interior was as no-nonsense as its exterior. The lobby featured a large picture window and stone wall, as well as relatively conservative furnishings. Guest rooms featured wood paneling, a wall-mounted pole lamp and a Raytheon television set. Epstein provided this rare photograph of the bathroom as built, as well as these other little-seen black and white renderings and photographs.

Progressive Architecture, 1958

Published photographs of many Shoreline Motels are extremely rare; as is often the case in Forgotten Chicago’s extensive research, non-digitized trade ads in long-gone architectural magazines are good sources of rarely seen images. The above photo was included in a 1958 advertisement in Progressive Architecture for the Rotary Lift Company, an elevator manufacturer still in business as of this writing. Worth noting is that the Shore Drive is actually nowhere near “downtown” Chicago.

Epstein’s 90-plus year history is a particular favorite of Forgotten Chicago. Epstein has designed everything from corporate headquarters, including as the 1955 Jewel Tea headquarters and warehouse in Melrose Park seen during our 2012 Corporate Kings of the Suburbs tour to the Hyatt Regency Chicago, McCormick Place South and West, and the 2008 Serta International Headquarters in Hoffman Estates.


Epstein’s Facebook page

Additionally, fifteen years after the opening of the Shore Drive Motel, Epstein would design one of Chicago’s first postwar shoreline hotels and what was also likely the shortest-lived modern hotel in the city. The enormous McCormick Inn once faced Lake Shore Drive at 23rd Street, and was demolished just 20 years after its 1973 opening for construction of McCormick Place South4. The McCormick Inn’s austere exterior does not hint at the remarkable and very period interior. For additional images, including earlier plans for this site, visit here.

In an elaborate publicity campaign during Epstein’s McCormick Inn’s construction, a Swissair stewardess is seen above left delivering dirt from Switzerland for the land under this new hotel. With a location then (and now) far from most of Chicago’s notable attractions, the McCormick Inn had the curious slogan upon opening of “Where Chicago’s Loop is seen and not heard.”

As mentioned, the Thunderbird and the Breakers (later 50th on the Lake) were built by the same developer and the same architect, Frank LaPasso. Unlike some of the other motels explored in this series, The Thunderbird could truly be considered a Shoreline Motel with Lake Michigan and the beach a short walk away, as seen above right in this 1962 aerial view.

Photographs of the Thunderbird are also extremely rare, and little is known about this motel in later years. Demolished by 1988 per aerial views5, the lot would remain vacant until the completion of the current Adam Clayton Powell, Jr. Paideia Academy in 2011.6

The southernmost Shoreline Motel was the Delta, which was completed in 1960. Designed by the architecture firm of Shayman & Salk, who also designed the Tropicana in Edgewater and TraveLodge on South Michigan Avenue. Shayman & Salk were also announced as architects of the controversial and ultimately unbuilt Sea & Sand Motel on the city’s far northeastern border.

Located at the high-traffic intersection of South Shore Drive (U.S. 41) and East 79th Street, the Delta was later called the the Breakers Motel, as seen in the closeup of the sign in the postcard below. When it closed, this motel was known as the Rainbow Beach Motel.7

It is not currently known when the Delta / Breakers / Rainbow Beach closed; it had disappeared from aerial views and was replaced by park land by 20058. The site of this former motel is near the northern terminus of the new extension of South Lake Shore Drive, which opened in 2013.

Above is a complete list of the known built and proposed Shoreline Motels on or near Chicago’s lakefront. The Shoreline Motel, like the four plus one apartment building and the municipal parking garage is one of the little studied building types that Forgotten Chicago specializes in researching.

As mentioned, we will publish a postscript on this series with an article on architect James Eppenstein, his forgotten transformation of Hyde Park’s Shoreland Hotel more than 75 years ago, and additional projects from his remarkable career.

Positive, negative, and neutral mutations during the evolution of coronaviruses like SARS-CoV-2.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes coronavirus disease 2019 (COVID-19), has many variants; some are or have been believed to be of particular importance. This article discusses such notable variants of SARS-CoV-2, and also discusses notable mutations found in some, or all, of these variants.

The sequence WIV04/2019, belonging to the GISAID S clade / PANGOLIN A lineage / Nextstrain 19B clade, is thought likely to reflect the sequence of the original virus infecting humans, known as 'sequence zero'.[1]

No consistent nomenclature has been established for SARS-CoV-2.[7] Colloquially, including by governments and news organizations, concerning variants are often referred to by the country in which they were first identified,[8][9][10] but as of January 2021[update], the World Health Organization (WHO) is working on 'standard nomenclature for SARS-CoV-2 variants that does not reference a geographical location'.[11]

While there are many thousands of variants of SARS-CoV-2,[12] subtypes of the virus can be put into larger groupings such as lineages or clades.[b] Three main, generally used nomenclatures[7] have been proposed:

  • As of January 2021[update], GISAID—referring to SARS-CoV-2 as hCoV-19[13]—had identified eight global clades (S, O, L, V, G, GH, GR, and GV).[14]
  • In 2017, Hadfield et al. announced Nextstrain, intended 'for real-time tracking of pathogen evolution'.[15] Nextstrain has later been used for tracking SARS-CoV-2, identifying 11 major clades[c] (19A, 19B, and 20A–20I) as of January 2021[update].[16]
  • In 2020, Rambaut et al. of the Phylogenetic Assignment of Named Global Outbreak Lineages (PANGOLIN)[17] software team proposed in an article[18] 'a dynamic nomenclature for SARS-CoV-2 lineages that focuses on actively circulating virus lineages and those that spread to new locations';[7] as of February 2021[update], six major lineages (A, B, B.1, B.1.1, B.1.177, B.1.1.7) had been identified.[19]

Notable variants

501.V2 variant

On 18 December 2020, the 501.V2 variant, also known as 501.V2, 20H/501Y.V2 (formerly 20C/501Y.V2), VOC-202012/02 (PHE), or lineage B.1.351,[20] was first detected in South Africa and reported by the country's health department.[21] Researchers and officials reported that the prevalence of the variant was higher among young people with no underlying health conditions, and by comparison with other variants it is more frequently resulting in serious illness in those cases.[22][23] The South African health department also indicated that the variant may be driving the second wave of the COVID-19 epidemic in the country due to the variant spreading at a more rapid pace than other earlier variants of the virus.[21][22]

Scientists noted that the variant contains several mutations that allow it to attach more easily to human cells because of the following three mutations in the receptor-binding domain (RBD) in the spike glycoprotein of the virus: N501Y,[21][24] K417N, and E484K.[25][26] The N501Y mutation has also been detected in the United Kingdom.[21][27]

Cluster 5

In early November 2020, Cluster 5, also referred to as ΔFVI-spike by the Danish State Serum Institute (SSI),[28] was discovered in Northern Jutland, Denmark, and is believed to have been spread from minks to humans via mink farms. On 4 November 2020, it was announced that the mink population in Denmark would be culled to prevent the possible spread of this mutation and reduce the risk of new mutations happening. A lockdown and travel restrictions were introduced in seven municipalities of Northern Jutland to prevent the mutation from spreading, which could compromise national or international responses to the COVID-19 pandemic. By 5 November 2020, some 214 mink-related human cases had been detected.[29]

The World Health Organization (WHO) has stated that cluster 5 has a 'moderately decreased sensitivity to neutralizing antibodies'.[30] SSI warned that the mutation could reduce the effect of COVID-19 vaccines under development, although it was unlikely to render them useless. Following the lockdown and mass-testing, SSI announced on 19 November 2020 that cluster 5 in all probability had become extinct.[31] As of 1 February 2021, authors to a peer-reviewed paper, all of whom were from the SSI, assessed that cluster 5 was not in circulation in the human population.[32]

Lineage B.1.1.207

First sequenced in August 2020 in Nigeria,[33] the implications for transmission and virulence are unclear but it has been listed as an emerging variant by the US Centers for Disease Control.[34] Sequenced by the African Centre of Excellence for Genomics of Infectious Diseases in Nigeria, this variant has a P681H mutation, shared in common with UK's VOC-202012/01. It shares no other mutations with VOC-202012/01 and as of late December 2020 this variant accounts for around 1% of viral genomes sequenced in Nigeria, though this may rise.[33]

Lineage B.1.1.7 / Variant of Concern 202012/01

First detected in October 2020 during the COVID-19 pandemic in the United Kingdom from a sample taken the previous month,[35]Variant of Concern 202012/01 (VOC-202012/01),[36] was previously known as the first Variant Under Investigation in December 2020 (VUI – 202012/01)[37] and also as lineage B.1.1.7 or 20I/501Y.V1 (formerly 20B/501Y.V1).[38][39][20] Since then, its prevalence odds have doubled every 6.5 days, the presumed generational interval.[40][41] It is correlated with a significant increase in the rate of COVID-19 infection in United Kingdom, associated partly with the N501Y mutation. There is some evidence that this variant has 30–70% increased transmissibility,[citation needed][42] and early analyses suggest an increase in lethality.[42] Variant of Concern 202102/02 (VOC-202102/02), described by Public Health England (PHE) as 'B.1.1.7 with E484K'[43] is of the same lineage in the Rambaut classification system but has an additional E484K mutation. There are 26 confirmed cases of VOC-202102/02 in the UK.[43]

Lineage B.1.429 / CAL.20C

CAL.20C, also known as lineage B.1.429, is defined by five distinct mutations, including L452R (which had previously been detected in unrelated lineages).[4][44] CAL.20C is possibly more transmissible, but further study is necessary to confirm this.[44] It was first observed in July 2020 by researchers at the Cedars-Sinai Medical Center, California, in one of 1,230 virus samples collected in Los Angeles County since the start of the COVID-19 epidemic.[45] It was not detected again until September when it reappeared among samples in California, but numbers remained very low until November.[46][47] In November 2020, the CAL.20C variant accounted for 36 percent of samples collected at Cedars-Sinai Medical Center, and by January 2021, the CAL.20C variant accounted for 50 percent of samples.[44] In a joint press release by University of California, San Francisco, California Department of Public Health, and Santa Clara County Public Health Department,[48] the variant was also detected in multiple counties in Northern California. From November to December 2020, the frequency of the variant in sequenced cases from Northern California rose from 3% to 25%.[49] In a preprint, CAL.20C is described as belonging to clade 20C and contributing approximately 36% of samples, while an emerging variant from the 20G clade accounts for some 24% of the samples in a study focused on Southern California. Note however that in the US as a whole, the 20G clade predominates, as of January 2021.[4] Following the increasing numbers of CAL.20C in California, the variant has been detected at varying frequencies in most US states and small numbers have been detected in other countries in North America, Europe, Asia and Australia.[46][47]

Lineage B.1.525

B.1.525, also called VUI-202102/03 by Public Health England (PHE) and formerly known as UK1188,[43] is partially similar to the 501.V2 variant, but differs by having both the E484K-mutation and a new F888L mutation (a substitution of phenylalanine (F) with leucine (L) in the S2 domain of the spike protein). As of February 16, it had been detected in 16 countries, including the UK, Denmark, Finland, Norway, Netherlands, Belgium, France, Spain, Nigeria, Ghana, Jordan, Japan, Singapore, Australia, Canada and the US.[50][51][52][53][54] The first cases were detected in December 2020 in the UK and Nigeria, and as of 15 February, it had occurred in the highest frequency among samples in the latter country.[52] As of 17 February, 46 cases were found in the UK.[43] Denmark, which sequence all their COVID-19 cases, found 61 cases of this variant from January 14 to February 12, of which seven were directly related to foreign travels to Nigeria.[50]

UK experts are studying it to understand how much of a risk it could be. It is currently regarded as a 'variant under investigation', but pending further study it may become a 'variant of concern'. Prof Ravi Gupta, from the University of Cambridge spoke to the BBC and said B.1.525 appeared to have 'significant mutations' already seen in some of the other newer variants, which is partly reassuring as their likely effect is to some extent more predictable.[55]

Lineage P.1

Lineage P.1, termed Variant of Concern 202101/02 by Public Health England[43] and 20J/501Y.V3 by Nextstrain,[56] was detected in Tokyo on 6 January 2021 by the National Institute of Infectious Diseases (NIID). The new lineage was first identified in four people who arrived in Tokyo having travelled from the Brazilian Amazonas state on 2 January 2021.[57] On 12 January 2021, the Brazil-UK CADDE Centre confirmed 13 local cases of the P.1 new lineage in the Amazon rain forest.[58] This variant of SARS-CoV-2 has been named P.1 lineage (although it is a descendant of B.1.1.28, the name B.1.1.28.1 is not permitted and thus the resultant name is P.1) and has 17 unique amino acid changes, 10 of which in its spike protein, including N501Y and E484K.[58] The new lineage was absent in samples from March to November from Manaus, Amazonas state, but it was identified in 42% of the samples from December 2020 collected in the same city, suggesting a recent increase in frequency.[58]A separate preprint by Voloch et al. identified another sub-lineage of the B.1.1.28 lineage circulating in the state of Rio de Janeiro, Brazil, now named P.2 lineage,[59] that harbours the E484K mutation. The P.2 lineage is not directly related with the P.1 lineage identified in Manaus.[58][60] Although both lineages harbour the E484K mutation, the mutation was acquired independently through convergent evolution.[58][better source needed]

Notable missense mutations

D614G

D614G is a mutation that affects the spike protein of SARS-CoV-2. The frequency of this mutation in the viral population has increased during the pandemic. G (glycine) has replaced D (aspartic acid) in many countries, especially in Europe though more slowly in China and the rest of East Asia, supporting the hypothesis that G increases the transmission rate, which is consistent with higher viral titers and infectivity in vitro.[1] In July 2020, it was reported that the more infectious D614G SARS-CoV-2 variant had become the dominant form in the pandemic.[61][62][63][64] PHE confirmed that the D614G mutation had a 'moderate effect on transmissibility' and was being tracked internationally.[65]

The global prevalence of D614G correlates with the prevalence of loss of smell (anosmia) as a symptom of COVID-19, possibly mediated by higher binding of the RBD to the ACE2 receptor or higher protein stability and hence higher infectivity of the olfactory epithelium.[66]

Variants containing the D614G mutation are found in the G clade by GISAID[1] and the B.1 clade by the PANGOLIN tool.[1]

E484K

E484K has been reported to be an escape mutation (i.e., a mutation that improves a virus's ability to evade the host's immune system[67][68]) from at least one form of monoclonal antibody against SARS-CoV-2, indicating there may be a 'possible change in antigenicity'.[69] The P.1. lineage described in Japan and Manaus,[70] the P.2 lineage (also known as B.1.1.248 lineage, Brazil)[71] and 501.V2 (South Africa) exhibit this mutation.[69] A limited number of B.1.1.7 genomes with E484K mutation have also been detected.[72] The name of the mutation, E484K, refers to an exchange whereby the glutamic acid (E) is replaced by lysine (K) at position 484.[73] Monoclonal and serum-derived antibodies are reported to be from 10 to 60 times less effective in neutralizing virus bearing the E484K mutation.[74][75] On 2 February 2021, medical scientists in the United Kingdom reported the detection of E484K in 11 samples (out of 214,000 samples), a mutation that may compromise current vaccine effectiveness.[76][77]

N501Y

N501Y denotes a change from asparagine (N) to tyrosine (Y) in amino-acid position 501.[65] This change is believed by PHE to increase binding affinity because of its position inside the spike glycoprotein's receptor-binding domain, which binds ACE2 in human cells; data also support the hypothesis of increased binding affinity from this change.[78] Variants with N501Y include P.1 (Brazil/Japan),[69][79] Variant of Concern 202012/01 (UK), 501.V2 (South Africa), and COH.20G/501Y (Columbus, Ohio). This last became the dominant form of the virus in Columbus in late December 2020 and January and appears to have evolved independently of other variants.[80][81]

New variant detection and assessment

On 26 January 2021, the British government said it would share its genomic sequencing capabilities with other countries in order to increase the genomic sequencing rate and trace new variants, and announced a 'New Variant Assessment Platform'.[82] As of January 2021[update], more than half of all genomic sequencing of COVID-19 was carried out in the UK.[83]

Differential vaccine effectiveness

A preliminary study by Pfizer, Inc. has indicated that there is, at most, only minor reduction of the company's mRNA vaccine effectiveness against different SARS-CoV-2 variants.[84] Another study of the effectiveness of the same Comirnaty vaccine against the Variant of Concern 202012/01 confirmed this.[85] According to the US CDC, most experts believe that, due to the nature of the virus, the emergence of variants that completely escape the immune response (both natural and vaccine induced) is considered unlikely.[86]

South Africa halted their deployment of the Oxford–AstraZeneca vaccine in early February after a study involving 2,000 people returned 'disappointing' results against the local variant.[87]

T-cell immunity is under investigation as a potential solution to the problem of reduced effectiveness of vaccines against the relevant variants. Biotechnology firm Gritstone is experimenting to develop a vaccine aimed specifically at creating T-cell immunity.[88]

On January 29, 2020, a deputy of the Moscow City Duma, Darya Besedina, turned to the Russian Minister of Health with a request to fund the study of new strains and conduct research on the effectiveness of Russian vaccines against these strains[89]. On February 10, 2020, the European Medicines Agency made a similar appeal to vaccine manufacturers[90]. On February 15, Russian President Vladimir Putin instructed the government to deploy the sequencing of the genomes of Russian SARS-CoV-2 strains within a month, allocate funds for these studies, and also check whether Russian vaccines are effective against new strains.[91]
