William Powell (1907-1992) was Mayor of Hamilton, Canada, from 1980 to 1982.

Born in St. Helen’s, Lancashire, England, his family emigrated to Canada in 1911. While his family returned to England, Powell came to Hamilton in 1921, and eventually found work at Stelco, a steel company based in Hamilton.

In 1958, he ran as the Co-operative Commonwealth Federation candidate in Hamilton East. He placed third with 21.6% of the vote, losing to incumbent Quinto Martini, a Progressive Conservative. Two years later, he was elected as an alderman in Ward 4. He served in this post until 1970. During his time as alderman, he also retired from his work at Stelco.

In 1970, he ran for a seat on the Board of Control, but was unsuccessful. Following his defeat, he assumed the Chairmanship of the Hamilton Region Conservation Authority and stayed in that position for a decade.

In 1980, he defeated incumbent mayor, Jack MacDonald. He served until 1982, when he was defeated by Bob Morrow.

In 1985, he was appointed as alderman for Ward 3 in order to fill a vacancy.

William Horatio Powell (July 29, 1892 – March 5, 1984) was a three-time Academy Award-nominated American actor, noted for his sophisticated, cynical roles. He is most widely known for portraying the detective Nick Charles in six The Thin Man films.

William Powell was on the New York stage in 1912 and it would be ten years before his film career would begin. In 1924 he would go to Paramount Pictures, where he would be employed for the next seven years. During these years he played in a number of interesting films, but stardom was elusive. He did attract attention with Last Command, The (1928) as Leo, the arrogant film director. Stardom would come with his role as Philo Vance in Canary Murder Case, The (1929), where he investigates the death of Louise Brooks (I), "the Canary". Unlike many silent actors, sound boosted Powell's career. He had a fine, urbane voice and his stage training and comic timing greatly aided his introduction to sound pictures. However, he was not happy with the type of roles he was playing at Paramount, so in 1931 he switched to Warner Bros. He would again be disappointed with his roles and would make his last appearance as Philo Vance in Kennel Murder Case, The (1933). In 1934 Powell went to MGM, where he would be teamed with Myrna Loy in Manhattan Melodrama (1934). While Philo made Powell a star, another detective, Nick Charles, made him famous. He would receive an Academy Award nomination for Thin Man, The (1934) and star in the Best Picture winner for 1936, Great Ziegfeld, The (1936). Powell could play any role with authority, whether in a comedy, thriller or drama. He would receive his second Academy Award Nomination for My Man Godfrey (1936). He was on top of the world until 1937. His first picture with Jean Harlow was Reckless (1935) and they clicked offscreen as well as onscreen, and shortly became engaged. While he was filming Double Wedding (1937) on one MGM sound stage, Harlow became ill on another and finally went to the hospital, where she died. Her death greatly upset both Powell and Myrna Loy and he would be off the movie for six weeks to deal with his sorrow. After that he would travel and did not make another MGM film for a year. He would do four sequels to "The Thin Man", with the last one being made in 1947. He would also receive his third Academy Award nomination for his work in Life with Father (1947). After that, his screen appearances became fewer and his last role was in 1955. He had come a long way from playing the villain in 1922.
