Russian-born British motion picture, television, and theatrical producer.

The son of a Jewish tailor's assistant, he immigrated with his family to England in 1912 and dropped out of school at age 14 to help in the family business. At age 20 he changed his name to Grade and went into vaudeville as a Charleston dancer. Soon he began representing other theatrical performers as a talent agent, and with his brother Leslie he went on to build Lew and Leslie Grade Ltd., which became the largest talent agency in Europe in the years after World War II. In the 1950s Grade became involved in British commercial television; his company, Associated Television (ATV), went on to produce several action-adventure series, including Robin Hood, The Saint, The Avengers, The Prisoner, and Danger Man (U.S. title Secret Agent). Two of the best-known series he produced were Coronation Street (the longest-running television program in the United Kingdom) and The Muppet Show.

Grade was also one of the few successful British motion picture producers in the late 20th century, producing such films as Desperate Characters (1971), The Tamarind Seed (1974), The Return of the Pink Panther (1975), The Eagle Has Landed (1976), The Boys From Brazil (1978), Autumn Sonata (1978), The Muppet Movie (1979), On Golden Pond (1981), and Sophie's Choice (1982). The money lost, however, on his 1980 film, Raise the Titanic, caused him to sell his production company in 1982. Grade then became chairman of Embassy Communications International until 1985, when he formed the Grade Co. He was knighted in 1969 and created a life peer in 1976.
