(Whitney) Lee Savage (1928 - 1998), was a painter and filmmaker. Among other things, he created animated shorts for Sesame Street. His son, Adam Savage, known for his role in MYTHBUSTERS on the Discovery Channel, supposedly voiced many of the child characters in these SESAME STREET shorts, while Lee voiced the adult parts, including the Dad's voice in BABY CLIMBS THE STAIRS.
According to his son, Adam, Savage, [Lee Savage] "directed, inked and animated the Mickey Mouse film which he co-wrote with Milton [Glaser]. My dad died in 1999 after a long bout with Alzheimer's and was always very proud of the Mickey film." (Cory Doctorow, Boing Boing, June 22, 2013)
