At a meeting in this hotel on July 16, 1936, Rose Schneiderman was elected vice chairman of the New York State Labor Party. The newly formed party declared its support for President Franklin Roosevelt and New York Governor Herbert Lehman, but called on all working people to desert the two established parties and join in a new coalition. The party's platform, developed during the same meeting, supported New Deal legislation and called for the extension of Social Security, further economic reform, and unemployment relief. The platform also defined the party's purpose as "to mobilize the political power of labor and the progressive forces of the people everywhere, in the cities and on the farms, against reaction and for freedom, against economic oppression and for recovery and democracy."

When Franklin Roosevelt became President in 1933, he named Schneiderman as the only woman on the National Labor Advisory Board. In that role, Schneiderman had a profound influence on New Deal legislation, writing the labor codes for every industry that had a predominantly female work force. She also helped to shape Social Security and the Fair Labor Standards Act.  She died on August 11, 1972.
