Dear Chris, when I first came to NY in the 60s, I knew another architect named Albert Kahn. The son of the one you wrote about. He was definitively not self educated.
Also, when we first moved to Riverside Dr. I was told that it was built in
the late 19th century for the rich Jews, Catholics and show biz folk who
werent allowed to live on Fifth or Park. If so, how come they let Moorish
synagogues go up?
