[Franklin D. Roosevelt] had to persuade people to feel comfortable in his presence…. [The therapists and he] began to work on his gait, to work on the way he would walk with the canes and crutches and assistance he would use. So his walk, although slow, began to look more and more natural. And he would seat himself, and he would throw up his head, he would begin to talk — he was always talking, actually — to put people at ease. And this whole physical routine that he developed of putting people at ease was enormously effective, and it made people forget that he was disabled.
