Oh trust me, I have. FLW was not a nice man by any means; it’s easy to see why he embodied the “virtue of selfishness” that Rand admired so much.
My favorite apocryphal FLW story was when I toured Fallingwater; the tour guide pointed out the low doorways and told us that Wright specifically ignored his client’s request for doors that’d accommodate his 6-foot-plus height and made all of the doors about 5’10". When the client complained and asked why, Wright said “They’re perfect for me. I’m 5 foot 9 and nobody needs to be taller than that.”
