The French Chef was an influential early television cooking show created by Julia Child, and produced and broadcast by WGBH in Boston, Massachusetts, from 1963-1973. It was one of the first cooking shows on television. The French Chef introduced French cooking to the United States at a time when it was considered expensive restaurant fare, not suitable for home cooking. Child emphasized fresh and, at the time, unusual ingredients. The show grew out of some special presentations that Julia had done based on the book Mastering the Art of French Cooking, which she had co-authored, and went on to become the most recognized pioneering cooking show.The show was done live to videotape from start to finish, leaving little room for mistakes. Later, errors were still used as "teachable moments". Certain elements became leitmotifs: Julia's fondness for wine; her staunch defense of the use of butter; her standard issue "impeccably clean towel"; and her closing line at the end of every show, "Bon appetit."Child's emphasis on whole, fresh ingredients often led to markets running out of whatever particular meat, fish, or vegetable was featured when an episode aired.Child was neither French nor a chef, but had studied and taught cooking in France.The French Chef was in production and aired on the WGBH station of National Educational Television (which became PBS) in Boston from 1963 to 1973. Reruns continued on PBS until 1987. A 1971 episode of The French Chef was the first television show to be captioned for deaf viewers. The show aired in two formats, originally in black and white and later in color, and two companion cookbooks were written along with the show. The French Chef Cookbook was a show-by-show breakdown of the black and white series, while From Julia Child's Kitchen was a somewhat more ambitious work that took its cues from the color series but also added considerable extra material.
