Roger had the best collection of Nijinsky photographs in the world -- you can see his collection today at the Metropolitan Museum of Art in New York. Roger actually gave me two huge blowups, "Afternoon of a Faun" and "Scheherazade." I was a great fan of Nijinsky's, though I never heard him dance, of course. My mother was impressed with Roger's ankles. He'd been a ballet dancer, and when he crossed his legs, my mother would say, "I've never seen such handsome ankles on a man."
Ankles? OK, never mind.
Judging from what I can find online, I think Gordon is mistaken about the Met, and Dodge's collection is actually in the Jerome Robbins Dance Division at the New York Public Library at Lincoln Center. Also, while Dodge danced ballet, vaudeville and jazz himself, as a critic it seems he mostly devoted himself to jazz dancing. He began writing in the 20's and died in 1974.
I wonder if anyone has read Dodge's writing, or remembers it from back in the day and can tell us which publication(s) he wrote for.
