About Jack Cassidy

Lived 1927 – 1976 (aged 49). Jack Cassidy was an American singer, stage actor, film actor, television actor, actor and musician.

John Joseph Edward Cassidy (March 5, 1927 – December 12, 1976) was an American actor, singer and theatre director. He received multiple Tony Award nominations and won a Tony Award as well as a Grammy Award for his work on the Broadway production of the musical She Loves Me. He also received two Primetime Emmy Award nominations. He was the father of teen idols David Cassidy and Shaun Cassidy.

Early life Cassidy was born in New York City, the son of Charlotte (née Koehler) and William Cassidy. He was the youngest of five children. His father, an engineer at the Long Island Rail Road, was of Irish descent and his mother was of German ancestry.

Career Cassidy achieved success as a musical performer on Broadway. He appeared in Alive and Kicking, Wish You Were Here, Shangri-La, Maggie Flynn, Fade Out – Fade In, It's a Bird...It's a Plane...It's Superman, and She Loves Me, for which he won a Tony Award. He also received Emmy Award nominations for his television performances in the 1967-68 CBS Television Network series He & She and The Andersonville Trial.

On television, he became a frequent guest star, appearing in such programs as The Alfred Hitchcock Hour, Gunsmoke, Bewitched, Get Smart, That Girl, Hawaii Five-O, Cannon, Match Game, McCloud, and Barnaby Jones for an episode titled "Murder in the Doll's House" (1973).

The role of the vain, shallow, buffoon-like newsman Ted Baxter on TV's The Mary Tyler Moore Show (1970–1977) was reportedly written with Cassidy in mind. Cassidy had played a similar buffoonish character in the 1967–1968 sitcom He & She, but he turned down the role, feeling that it was not right for him; the part went to Ted Knight. Cassidy later appeared as a guest star in a 1971 episode as Ted's highly competitive and equally egotistical brother Hal.

Cassidy had 12 grandchildren: Katie Cassidy and Beau by his first son David; Caitlin, Jake, Juliet, Caleb, Roan, Lila, and Mairin Cassidy by son Shaun; Cole and Jack by son Patrick; and, Meghan Mae by son Ryan. His grandson, Jack Cassidy, was a contestant on the singing competition television show The Voice in 2017.

Mental health In his 1994 autobiography, C'Mon, Get Happy, Cassidy's eldest son David wrote that he became increasingly concerned about his father in the last years of his life. The elder Cassidy, who suffered from bipolar disorder and alcoholism, was displaying increasingly erratic behavior. In 1974, his neighbors were shocked to see him fully naked, watering his front lawn in the middle of the afternoon. Cassidy's second wife, Shirley Jones, described a similar incident when she found him sitting naked in a corner of their house, reading a book. Jones said to him that they had to get ready to do a show, and he calmly looked up and said, "I know now that I'm Christ". In December 1974, Cassidy was hospitalized in a psychiatric facility for 48 hours. At that time, Jones found out that he had been previously diagnosed with bipolar disorder.

Sexuality David Cassidy said his father was bisexual, citing personal accounts and reports, both anecdotal and published, of his father's same-sex affairs, something neither he nor his siblings knew until after their father's death. In her 2013 memoir, Shirley Jones wrote that Cassidy had many same-sex affairs, including one with Cole Porter.

Death On December 11, 1976, Cassidy invited his ex-wife, Shirley Jones, to his home, an apartment in West Hollywood, California, for drinks, but she declined.

Early the next morning, Cassidy lit a cigarette and fell asleep on his Naugahyde couch. Asleep, he dropped the cigarette, igniting the couch. The flames spread throughout the apartment and building. by dental records and a signet ring that he wore, bearing the Cassidy family crest. His remains were cremated and scattered in the Pacific Ocean.
