William Alvin Howard (born 1926) is a proof theorist best known for his work demonstrating formal similarity between intuitionistic logic and the simply typed lambda calculus that has come to be known as the Curry–Howard correspondence. He has also been active in the theory of proof-theoretic ordinals. He earned his Ph.D. at the University of Chicago in 1956, where he was a student of Saunders Mac Lane.
The Howard ordinal (also known as the Bachmann–Howard ordinal) was named after him.

“He [Roosevelt] has made some speeches that indicate that he is going quite beyond anything that he advocated when he was in the White House, and has proposed a program which is absolutely impossible to carry out except by a revision of the Constitution.”
—William Howard Taft (1857–1930)
