Who choreographed Fiorello!?

Fiorello! is a musical about New York City mayor Fiorello La Guardia, a reform Republican, which debuted on Broadway in 1959, and tells the story of how La Guardia took on the Tammany Hall political machine. The book is by Jerome Weidman and George Abbott, drawn substantially from the 1955 volume Life with Fiorello by Ernest Cuneo, with lyrics by Sheldon Harnick, and music by Jerry Bock. It won the three major theatre awards - Tony Award (shared with The Sound of Music), the New York Drama Critics Circle award, and the Pulitzer Prize for Drama. It is one of only ten musicals to win the latter award.
