Robert Reiniger Meredith Willson (May 18, 1902 – June 15, 1984) was an American flautist, composer, conductor, musical arranger, bandleader, playwright, and writer. He is perhaps best known for writing the book, music, and lyrics for the 1957 hit Broadway musical The Music Man and "It's Beginning to Look a Lot Like Christmas" (1951). Willson wrote three other musicals, two of which appeared on Broadway, and composed symphonies and popular songs. He was twice nominated for Academy Awards for film scores.
