Siegel worked at a range of jobs throughout the 1960s, often concentrating on the civil rights movement. In the late '60s, before moving to New York, he worked as an advertising agency copywriter and producer. While working in advertising for Carson/Roberts Advertising, he invented and named ice cream flavors for Baskin-Robbins.[6] These flavors were: German Chocolate Cake; Peaches & Cream; Pralines & Cream; Blueberry Cheesecake; Strawberry Cheesecake; Green Cheesecake; Red, White and Blueberry; and Chilly Burgers.[7]
He began working in radio as a disc jockey and newscaster, while continuing to freelance in advertising. Through his freelance work, he was offered the book review position with the Los Angeles Times.
Siegel's essays in the Los Angeles Times Sunday Magazine were spotted by a CBS executive, and Siegel was hired as a feature correspondent for WCBS-TV in New York. Joel created signature work teamed with a producer who later became an executive at WABC-TV's Eyewitness News. When Siegel's producer moved, he offered Siegel a featured on-air position, and Joel accepted. Siegel proposed to Eyewitness News management that he become a film and theater critic. He suggested that he would innovate the form by using brief clips from the movie or show being reviewed as drop-ins into his reviews, working them into his scripts as gags to create a new, witty form of review. Siegel also, during his years at WCBS-TV, created features for WCBS-AM Newsradio 88 called Joel Siegel's New York.
Siegel's second wife, Jane Kessler, died from a brain tumor in 1982. In 1991, he joined with the actor Gene Wilder to found Gilda's Club, a nonprofit organization that provided social support for cancer patients and their families. The organization was named for Wilder's wife, Gilda Radner, who died of ovarian cancer.
On June 21, 1996, Siegel married his fourth wife, artist Ena Swansea. In 1997, at age 53, he was diagnosed with colorectal cancer. One week after being diagnosed, Siegel found out he would be a father for the first time. He wrote the book Lessons for Dylan which shares the ups and downs of his life with his young son, as he might not live long enough to relate those stories in person.[8]
Siegel underwent surgery, radiation, and chemotherapy. He welcomed his newborn son, Dylan Thomas Jefferson Swansea Siegel, home on the same day he completed his chemotherapy treatments. Two years later, a CAT scan revealed a lesion on Siegel's left lung. After a pulmonary lobectomy and additional chemotherapy, Siegel continued to work on GMA.
He was outspoken on the subject of colon cancer and, in 2005, spoke at a meeting of C-Change, a group of cancer experts from government, business, and non-profit sectors, chaired by former President George H.W. Bush and former first lady Barbara Bush.[9]
He testified before the Senate during Colorectal Cancer Awareness month, March 2005. "I came here from New York City this morning hoping that I would encourage someone to have a colonoscopy so that they would not have to go through what I went through," he told a Senate panel.[10]
In June 2005, Siegel published a letter in the peer-reviewed cancer medicine journal, The Oncologist entitled, "One at a Time". It shares his cancer diagnosis and experiences to that date.[11]
On May 10, 2007, less than two months before his death, he spoke before the CEO Roundtable on Cancer,[12] an association of corporate executives that was formed when former President George H. W. Bush asked corporate America to do something "bold and venturesome" about cancer. Bush and his wife Barbara were in the audience when Joel spoke on May 10 at the Essex House in New York City. He began and ended his presentation by saying, "I want to thank you for what you are doing for cancer patients."
Joel Siegel died from metastatic colon cancer on June 29, 2007 shortly before what would have been his 64th birthday. His family has said the last movie he saw was Ratatouille with his son.
