In The Power Broker, his massive biography of Robert Moses, Robert Caro recounts how, during the construction of the BQE, Moses rented a penthouse in the Marguerite Hotel in Brooklyn to use as an office: "He spent a lot of time looking down at it, watching the cranes and derricks and earth-moving machines that looked like toys far below him moving about in the giant trench being cut through mile after mile of densely packed houses, a big black figure against the sunset in the late afternoon, like a giant gazing down on the giant road he was molding."
I can't find any evidence online for a Marguerite Hotel. Looks like the magnificent Caro goofed and he is talking about the former Hotel Margaret in Brooklyn Heights, seen above in a pre-BQE image from 1930. The photo comes from the awesome City Noise website page about New York City in 1930. (BTW: Werner Herzog was the crazy white emperor referred to in previous post--not me. I think RM and WH would have a lot to talk about.)
