Robert Bernard Sherman (December 19, 1925 – March 6, 2012) was an American songwriter, best known for his work in musical films with his brother, Richard Morton Sherman. The Sherman brothers produced more motion picture song scores than any other songwriting team in film history. Some of their songs were incorporated into live action and animation musical films including Mary Poppins, The Happiest Millionaire, The Jungle Book, The Many Adventures of Winnie the Pooh, Chitty Chitty Bang Bang, The Slipper and the Rose, and Charlotte's Web. Their best-known work is "It's a Small World (After All)," possibly the most performed song (in public) in history.
