Singer with Jon Stone and Jim Henson.

Dulcy Singer served as the executive producer for Sesame Street from 1982 to 1993. She received her B.A. in English literature from Mount Holyoke College in 1955.

Singer also produced several direct-to-video and television specials, including Christmas Eve on Sesame Street, Don't Eat the Pictures, Sesame Street, Special, and Elmo's Sing-Along Guessing Game.

During her time as show runner of Sesame Street, she oversaw decisions to handle the death of Mr. Hooper on-screen, the adoption of Miles and the birth of Gabi and initially vetoed an idea for a script about divorce, which eventually never aired anyway.
