André Joyce is a possibly fictional, Franco-American writer and pataphysicist serving as a pseudonym for Michael Joseph Halm. He coined the words "googology" and "googologist", and some names of large numbers. His name is a pun on "and rejoice," a phrase appearing various times in the Christian Bible.
