Paul Tripp (February 20, 1911 – August 29, 2002) was a children's musician, author, songwriter, and television and film actor. He collaborated with a fellow composer, George Kleinsinger. Tripp was the creator of the 1945 "Tubby the Tuba", a piece of classical music for children that has become his best-known work. He authored several books, including Rabbi Santa Claus and Diary of a Leaf.
Tripp was born in New York City. He held a master's degree in education.
Early in his career, he was the host of Mr. I. Magination, which was aired by CBS from 1949 to 1952 featuring him as a train engineer who took children through a tunnel to meet with representatives of different occupations. Tripp later hosted Birthday House, a live (later taped) daily morning children's show on WNBC that aired in New York for four years starting in 1963. A book of his, The Christmas That Almost Wasn't, was produced as a movie in Rome in 1966, for which Tripp provided the screenplay and played a lead role.
