My deep thanks to Irving Aschheim for sharing the bounty of his encyclopedic memory; to Michael Stall and Hyman Bogen for helping me understand asylum life; to Jim Van Duyne for explaining the mysteries of classic luxury cars; to Steve Long of the Tenement House Museum for answering my questions about the Lower East Side and for directing my research into productive channels; to Kenny Kasowitz of the New York Transit Museum for telling me about travel by trolley and train in a younger New York City; to Nedda Sindin for her help with Yiddish and for her memories of New York City in the twenties; and to my friend and longtime colleague William Eller for his careful reading and insightful comments.
