Don Louis Agrati (June 8, 1944 – June 27, 2012), better known as Don Grady, was an American actor, composer, and musician. He was best known both as one of Mickey Mouse's original Mouseketeers, and as Robbie Douglas on My Three Sons. His sister was also an actress, billed as Lani O'Grady. Their mother was a talent agent, known as Mary Grady.
His acting credits included several Western series, including John Payne's The Restless Gun, Dick Powell's Zane Grey Theater, Wagon Train and The Rifleman, where he played a young man whose vocal cords were severed by Indians. He also had a role in the NBC medical drama, The Eleventh Hour. Originally the frustrated middle brother on My Three Sons, he became the confident elder brother with the departure of Mike (Tim Considine, who had earlier appeared with Grady in The New Adventures of Spin and Marty), and the adoption of Ernie (Barry Livingston), who became the new "third son."
After My Three Sons ended in 1972, Grady pursued a musical career. His works included music for the Blake Edwards comedy film Switch, the theme song for The Phil Donahue Show and for EFX, a Las Vegas multimedia stage show which starred Michael Crawford, David Cassidy, Tommy Tune, and Rick Springfield.
