Sherman died peacefully in his London home on Monday, according to his agent. His son Jeffrey paid tribute to his father on Facebook, saying he "wanted to bring happiness to the world and, unquestionably, he succeeded."
Sherman was one half of the successful song writing duo, "The Sherman Brothers." He and his brother Richard won two Academy Awards, and seven additional nominations, as well as three Grammy awards. The team penned over 150 Disney songs- including "Mary Poppins," "The Jungle Book," "The Aristocats," and "Chitty Chitty Bang Bang."
"What seems so simple is really very complex," his son Jeffrey said. "He was a very simple guy - complex but simple. If you ever want to know about my Dad, listen to the lyrics of his songs."
And then there's a tune Walt Disney asked "the boys," as the brothers were known, to write- the tongue twisting "Mary Poppins" song that's become their most memorable. They also wrote the most-played tune on Earth, "It's a Small World (After All)."
He was born in New York on Dec. 19, 1925, and was raised there and in Beverly Hills. Sherman moved to Britain in 2002 after the death of his wife Joyce. He is survived by his brother and four children: Laurie, Jeffrey, Andrea and Robert.
Disney is the parent company of ABC7.
