Kirk Douglas, one of the most famous actors of all time, passed away today at the age of 103.

“It is with tremendous sadness that my brothers and I announce that Kirk Douglas left us today at the age of 103,” his son, the famous actor, Michael Douglas, said in a statement. “To the world, he was a legend, an actor from the golden age of movies who lived well into his golden years, a humanitarian whose commitment to justice and the causes he believed in set a standard for all of us to aspire to.”

Kirk Douglas was born Issur Danielovitch on December 9, 1916. He was one of the last surviving stars of the film industry’s Golden Age. After an impoverished childhood with immigrant parents and six sisters, he made his film debut in The Strange Love of Martha Ivers (1946). Douglas soon developed into a leading box-office star throughout the 1950’s, known for serious dramas, including westerns and war movies. During his career, he appeared in more than 90 movies including Tough Guys, Spartacus, and Saturn 3.

Douglas became an international star through positive reception for his leading role as an unscrupulous boxing hero in Champion (1949), which brought him his first nomination for the Academy Award for Best Actor. Other early films include Young Man with a Horn (1950), playing opposite Lauren Bacall and Doris Day, Ace in the Hole opposite Jan Sterling (1951), and Detective Story (1951), for which he received a Golden Globe nomination as Best Actor in a Drama. He received a second Oscar nomination for his dramatic role in The Bad and the Beautiful (1952), opposite Lana Turner, and his third nomination for portraying Vincent van Gogh in Lust for Life (1956), which landed him a second Golden Globe nomination.

In 1955, he established Bryna Productions, which began producing films as varied as Paths of Glory (1957) and Spartacus (1960). In those two films he collaborated with the then-relatively-unknown director Stanley Kubrick, taking lead roles in both films. Douglas has been praised for helping to break the Hollywood blacklist by having Dalton Trumbo write Spartacus with an official on-screen credit. He produced and starred in Lonely Are the Brave (1962), considered a classic, and Seven Days in May (1964), opposite Burt Lancaster, with whom he made seven films. In 1963, he starred in the Broadway play One Flew Over the Cuckoo’s Nest, a story that he purchased and later gave to his son Michael Douglas, who turned it into an Oscar-winning film.

As an actor and philanthropist, Douglas received three Academy Award nominations, an Oscar for Lifetime Achievement, and the Presidential Medal of Freedom. As an author, he wrote ten novels and memoirs. He is No. 17 on the American Film Institute’s list of the greatest male screen legends of classic Hollywood cinema, the highest-ranked living person on the list until his death. After barely surviving a helicopter crash in 1991 and then suffering a stroke in 1996, he focused on renewing his spiritual and religious life. He lived with his second wife of 65 years, Anne Buydens, a producer, until his death today.
