A new building was erected on this site in 1836 and occupied by various importers. In the 1920s, insurance executive William H. McGee remodeled the site for his insurance firm. At mid-century, Lehman Brothers occupied the building (then known as 9 South William) as an annex to its larger building across Mill Lane. Originating as a mercantile trade and commodities firm before the Civil War, Lehman Brothers established a base in New York in 1868 and soon shifted to investment banking. The only such firm to survive the Great Depression with its prestige intact, they financed many successful businesses such as Hollywood studios and large department store chains.
The company, which occupied No. 1 William Street from 1928 to 1980, expanded into No. 9-11 South William Street in 1961. At the time of its sale to American Express in 1984, Lehman Brothers were Wall Street’s oldest continuing banking partnership. They subsequently sold the building and moved their offices elsewhere.
In the 1990s, Frances and Leon Birnbaum purchased the building. Survivors of the Holocaust, they immigrated to America in the 1950s. Through hard work and determination, they built a new life in New York. Starting as a peddler on the street, Leon became a successful businessman with Frances’ help. After a total renovation of the building, they opened The Wall Street Inn in 1999. Leon passed away in 2012. Frances passed away in 2023. Their family continues to own and operate The Wall Street Inn to this day. It is a proudly woman-owned business.
