Ronald Howard (7 April 1918 - 19 December 1996), the son of actor Leslie Howard, was an English actor and writer best known in the U.S. for starring in a weekly Sherlock Holmes television series in 1954.

The British actor Ronald Howard was born in Norwood, London, England, in 1918. He and his younger sister Leslie Ruth Howard were raised by their mother Ruth Evelyn Martin and their father, the renowned actor Leslie Howard (I). After college, Howard became a newspaper reporter for a while but decided to follow in his father's footsteps and become an actor. He got his first taste of acting when he appeared with his father in an uncredited bit part in 'Pimpernel' Smith (1941). In the early 1940s, Howard gained acting experience in regional theater, later on the London stage, and eventually in films, with his official debut in While the Sun Shines (1947). His chief claim to fame is in television with his portrayal of Sherlock Holmes in the series "Sherlock Holmes" (1954), in which Howard Marion-Crawford played Dr. Watson. Boyishly handsome with a pleasant demeanor, Howard continued in film and television until the mid-1970s; however, he never caught on with audiences as well as his father had, prompting him to put aside his acting career to run an art gallery. In the 1980s, he wrote a biography of his father.
