Harold Block (August 2, 1913 – June 16, 1981) was an American comedy writer, comedian, producer, songwriter and television personality. Although Block was a highly successful comedy writer for over 15 years, today he is most often remembered as an original panelist of the television game show What's My Line? who was fired from the show in its third season, reportedly for inappropriate on-air behavior. Block is a controversial figure in the history of television, denounced by some, while praised by others as a writer and for contributing to the original success of What's My Line? During the 1940s, Block was considered one of America's best comedy writers, having worked for many of the top comedians of the era, such as Bob Hope, Abbott and Costello, Martin and Lewis, Milton Berle and Burns and Allen and in all major media, including radio, Hollywood movies, Broadway and print. Block also made major contributions to the USO during World War II. In March 1950, producers of the new game show What's My Line? hired Block for its fourth episode to add humor to the show's format. With a panel previously consisting of journalists, a politician and a poet, reviewers had criticized the show as bland. After a rocky start, What's My Line? became one of the top-rated shows on television. Critics praised his work; the Chicago Sun-Times called Block the "freshest new personality in TV." However, his humor could be risqué, which antagonized some conservative 1950s viewers. He once risked the sponsor's wrath, referring to their deodorant with the line "Make your armpit a charmpit." In early 1953, Block was suspended and then fired. He left show business for the investment business a few years later, while What's My Line? continued on as a staple of Sunday night television for another 14 years. Background Block was born on August 3, 1913 in Chicago and raised in the Hyde Park area. According to Gil Fates, executive producer of the What's My Line? television game show, there were rumors Block had come from a wealthy family. Three comedy writing contemporaries of Block, Melvin Frank, Norman Panama, and Bob Weiskopf, also came from Hyde Park. Block attended the University of Chicago High School, graduating in 1930, and then the University of Chicago where he majored in law, graduating in 1935. At the University of Chicago he was co-captain of the university track team, running the
