Raymond Massey:
Raymond Hart Massey was born on August 30, 1896 in Toronto. His father was Hart Massey, the owner of the Massey-Ferguson Tractor Company. Young Raymond grew up in comfort, as a member of one of Canada’s wealthiest families of the time.

Massey started acting while attending Appleby College in Oakville. He then attended at the University of Toronto and then Balliol College in Oxford, England, where he continued acting.

With the outbreak of The First World War, he enlisted in the Canadian Field Artillery. His brother, Vincent also served during World War I. While on duty in Siberia, Raymond broke the monotony of army life and appeared in an army minstrel show entertaining the American troops who were on occupation duty. Severely wounded in action in France he was shipped home where he eventually worked in the family business, selling farm implements. His brother, Vincent, would also join the family firm following the war, and become its president in the early 1920s.

But Raymond missed the stage and so, he returned to acting. In 1922, he made his stage debut in London. Through most of the 1920s he honed his abilities in innumerable stage appearances. His first movie role was High Treason in 1927, and he played Sherlock Holmes in The Speckled Band in the following year. But he was soon back in theatre working before an audience.

In the 1930s, he played in a total of 12 films including starring or co-starring classics like The Scarlett Pimpernel in 1934, Things to Come, and Fire Over England in 1936, and The Prisoner of Zenda in 1937, alternating between England and Hollywood.

In 1940, back in the United States, Massey played Abraham Lincoln in Abe Lincoln in Illinois. Ironically, early in Massey's career, Abraham Lincoln's son, Robert Todd Lincoln (1843-1926), heard Massey perform and was struck by the close similarity of Massey's speaking voice to that of his father. Massey was nominated for an Academy Award for his work in this film. A year later brought his powerful performance in The Forty-Ninth Parallel.

During World War II, Massey rejoined the Canadian Army, and was wounded and invalided out in 1943. Following the war, he became an American citizen. He returned however, to England for A Matter of Life and Death in 1946, excelling in his small part.

Massey decided to serve as narrator for A Canterbury Tale in 1944 and then accepted a role in the now classic Arsenic and Old Lace. Raymond's early military experience served as a solid foundation for his role in 1947 as Brigadier General Ezra Mannon in Mourning Becomes Electra. Later that same year he appeared in the cinematic version of Ayn Rand's The Fountainhead. He worked steadily throughout the 50s, and was most effective when he appeared with James Dean in 1955's East of Eden.

Not limited to just the big screen, he became well known on television in the 1950s and 1960s. Massey also appeared in the hit series, I Spy which made its debut in 1966. He spent five years as Dr. Gillespie on Dr. Kildare from 1961 to 1966.

He narrated Jacqueline Kennedy's Asian Journey in 1962, after having reprised his role as Abe Lincoln in How the West Was Won. His last film was Mackenna's Gold in 1969. With his career winding down, he made a few made-for-TV movies, the last in 1973.

Raymond Massey died from pneumonia on July 29, 1983, in Los Angeles, California, at age 87. He is buried in New Haven, Connecticut. Massey had married three times. Children Daniel Massey and Anna Massey, both born in England, in the 1930s, became successful actors.

Massey has two stars on the Hollywood Walk of Fame, one for movies at 1719 Vine Street and one for television at 6708 Hollywood Blvd.

After running the family business for a number of years, Massey’s brother Vincent went on to be the first Canadian-born Governor General of Canada, serving from 1952 to 1959. The family name graces Toronto's Massey Hall, a historic concert hall bought by his grandfather in 1894 for $150,000.
