William Horatio Powell (July 29, 1892 – March 5, 1984) was an American actor, known primarily for his film career. Under contract with Metro-Goldwyn-Mayer, he was paired with Myrna Loy in 14 films, including the Thin Man series based on the Nick and Nora Charles characters created by Dashiell Hammett. Powell was nominated for the Academy Award for Best Actor three times: for The Thin Man (1934), My Man Godfrey (1936), and Life with Father (1947).

Powell was born in Pittsburgh in 1892,^[1] the only child of Nettie Manila (née Brady) and Horatio Warren Powell, an accountant.^[2][3] In 1907, young William moved with his family to Kansas City, Missouri, where he graduated from Central High School four years later.^{[citation needed]}

After high school, Powell enrolled at the University of Kansas to study law, but after a week he relocated to New York City, where he attended the American Academy of Dramatic Arts.^[3][4] In 1912, Powell left the AADA, and began working in vaudeville and stock companies.^[5] He also appeared on Broadway.^[6][7] Powell began his Hollywood career in 1922, in a production of Sherlock Holmes with John Barrymore. He performed as Francis I in When Knighthood Was in Flower with Marion Davies.^[8]

Powell remained under contract to Paramount throughout the 1920s, before signing with Warner Bros.

Powell portrayed a vengeful film director in the silent movie The Last Command (1928). His first starring role was Philo Vance in The Canary Murder Case (1929). He played Vance at Paramount Pictures four times. His strong stage-developed voice became a powerful asset when talking pictures were introduced.

Powell appeared as Nick Charles in six Thin Man films, beginning with The Thin Man in 1934, based upon Dashiell Hammett's novel. This movie provided Powell with his first Academy Award nomination, in 1935^[9]

Powell starred in The Great Ziegfeld, (1936), opposite his The Thin Man co-star, Myrna Loy, who played Ziegfeld's wife, Billie Burke. In 1937, Powell received his second Academy Award nomination for the comedy My Man Godfrey.^[10]

In 1935, he starred with Jean Harlow in Reckless. In 1936, Harlow and Powell appeared in Libeled Lady, and they became romantically involved off-set. He gave her a handsome ring, but did not ask her to marry him, so she referred to it as her "unengagement ring". Powell had been unhappy with his previous marriage to popular actor Carole Lombard, and this apparently kept him from entering a similar arrangement with Harlow, who was a sex symbol to the film-going public during that time. They kept company but did not live together. Harlow fell ill from undiagnosed kidney failure while working on a film with Clark Gable, and died before the film was completed, from uremia, at age 26 in June 1937.^[11]

Powell received his third Academy Award nomination in 1947 for his role as Clarence Day Sr. in Life with Father.^[12] His last film was playing the character Doc in 1955's Mister Roberts.

On April 15, 1915, Powell married Eileen Wilson, who was born Julia Mary Tierney. The couple had a son, William David Powell. They divorced in 1930. Powell's son became a television writer and producer before a period of ill health and depression led to his suicide in 1968.^[13]

On June 26, 1931, Powell married actress Carole Lombard. They divorced in 1933, but starred in My Man Godfrey three years later. Powell was devastated by her death in an airplane crash in 1942.^[14] He was romantically involved with Jean Harlow, his co-star in Reckless (1935), until her unexpected death from illness in 1937.^[15][16] On January 6, 1940, three weeks after they met, Powell married his third wife, actress Diana Lewis, who cancelled her film career to be his full-time wife. They remained married until his death in 1984.^[17]

A Republican, Powell supported Thomas Dewey in the 1944 United States presidential election^[18] and the 1948 United States presidential election.^[19]

In March 1938, Powell was diagnosed with rectal cancer.^[4][20] He underwent surgery and experimental radium treatment, which put the disease in full remission within two years. Given his own health and sorrow over Jean Harlow's death, Powell did not undertake any film roles for more than a year during this period.^[21]

Powell died in Palm Springs, California, on March 5, 1984, at the age of 91 from pneumonia. He is buried at the Desert Memorial Park in Cathedral City, California, near his third wife, Diana Lewis, and his only child, William David Powell.^[1][22]
