Hey Mike,
I just thought you might like to know this book exists (if you didn't already):
'The compulsive hermits came from a respected, well-to-do family and were educated at Columbia, Homer as a lawyer and Langley, who was a talented pianist, as an engineer. They became part of New York lore in August 1938, when the World-Telegram wrote about the pair and their once-fashionable house on Fifth Avenue and 128th Street, which was crammed full of pianos, other instruments, bicycles, chandeliers, clocks and thousands of newspapers, "strewn in yellowing drifts across the floor."'
