Julia Child (1912–2004) was a famous chef who wrote several cookbooks and appeared on a number of her own television cooking shows beginning in 1963.
As recounted in Street Gang: The Complete History of Sesame Street, one of Child's recipes was served at a dinner party on the night that the idea for Sesame Street was first discussed. Entertaining Lloyd Morrisett and his wife, Joan Ganz Cooney "served up a delectable boeuf bourguignon, beef stew in red wine with bacon, onions, and mushrooms, a traditional French recipe — which, as it happens, appears on page 315 of the first volume of Mastering the Art of French Cooking. Let history note, then, that Julia Child, public television's grande dame, provided the savory sauce poured on the night Sesame Street was conceived."
The week of January 21, 1974, Child appeared at a two-day event in Washington, D.C. for public broadcasting in which she performed in a skit with Cookie Monster. The skit featured a vocal duet, and ended with Child pouring ingredients down Cookie Monster's mouth. Vice President Gerald R. Ford also attended the event.
