Biography
Eugene Kal Siskel (January 26, 1946 – February 20, 1999) was an American film critic and journalist for the Chicago Tribune who co-hosted a movie review television series alongside colleague Roger Ebert.
Siskel started writing for the Chicago Tribune in 1969, becoming its film critic soon after. In 1975, he was paired with Roger Ebert to co-host a monthly show called Opening Soon at a Theater Near You airing locally on PBS member station WTTW. In 1978, the show, renamed Sneak Previews, was expanded to weekly episodes and aired on PBS affiliates across the United States. In 1982, Siskel and Ebert left Sneak Previews to create the syndicated show At the Movies. Following a contract dispute with Tribune Entertainment in 1986, Siskel and Ebert signed with Buena Vista Television, creating Siskel & Ebert & the Movies (renamed Siskel & Ebert in 1987, and renamed again several times after Siskel's death).
Known for their biting wit, intense professional rivalry, heated arguments, and trademark "Thumbs Up or Thumbs Down" movie ratings system, Siskel and Ebert became celebrated in American pop culture. Siskel was diagnosed with brain cancer in May 1998 but remained in the public eye as Ebert's professional partner until his death the following year.
