Who is this?

His abandoned plans for a new York Skyscraper hotel is believed to have influenced the redesign of the WTC after the 9/11 Attacks. When he was 74 years old, he was run over by a tram. Because of his ragged clothes and empty pockets, the cab drivers refused to take him to a hospital fearing he would be unable to pay. His friends when they found him in a general hospital wanted to move him to a better place but he declined saying he belonged among the poor. He was later buried in the middle of his most famous work. Who was he?
