Not sure if this is an appropriate place to post since he’s a writer and not a bar or bartender, but I always think it’s interesting how reading about cocktails can lead down random rabbit holes. I was looking into sources for a train related thing and was looking up books on the Twentieth Century when I found a book written by Lucius Beebe.
I recognized the name as being the author of the Stork Club Bar Book which is what I always thought him as being known for, but apparently the majority of his books were on trains. Super interesting character who had a larger than life personality, lived openly as a gay man, and traveled the country with his partner on a private train car that he owned.
This is a short bio that touches on his writing re: cocktails and New York nightlife.

And below is a Google Books link to a Life article with great photos of a party he threw on a random short line railroad.
