Tesla remained bitter in the aftermath of his incident with Edison. The day after Edison died the
New York Times contained extensive coverage of Edison's life, with the only negative opinion coming from Tesla, who was quoted as saying, "He had no hobby, cared for no sort of amusement of any kind and lived in utter disregard of the most elementary rules of hygiene... His method was inefficient in the extreme, for an immense ground had to be covered to get anything at all unless blind chance intervened and, at first, I was almost a sorry witness of his doings, knowing that just a little theory and calculation would have saved him 90 per cent of the labor. But he had a veritable contempt for book learning and mathematical knowledge, trusting himself entirely to his inventor's instinct and practical American sense."
Shortly before Edison died, he said that his biggest mistake he had made was never respecting Tesla or his work.
