Hollywood actor Kirk Douglas is celebrating his 100th birthday today.

The screen veteran has racked up a career spanning seven decades that included three Oscar nominations, as well as an honorary Academy Award in 1996 for being "a creative and moral force in the motion picture community".

Best known for his roles in Spartacus (1960) and 20,000 Leagues Under The Sea (1954), Kirk earned his Oscar nominations for best actor in Champion (1949), The Bad And The Beautiful (1952), and Lust For Life (1956), but lost out on the trophy each time.

He was born Issur Danielovitch in 1916 in Amsterdam, New York, to Jewish immigrant parents Herschel and Bryna, who had left Chavusy in the Mogilev Region of the Russian Empire, which is modern-day Belarus.

The Danielovitch family also had six daughters and lived in poverty, with father Herschel working as a ragman.

After enlisting in the United States navy in 1941, Issur changed his name to Kirk Douglas and was a communications officer in anti-submarine warfare during the Second World War until he was medically discharged because of his injuries in 1944.

Kirk had attended the American Academy of Dramatic Arts in New York City on a special scholarship, where two of his classmates were Diana Dill, who became his first wife in 1943, and Lauren Bacall, who helped to launch his film career.

He and Diana had two sons together - actor Michael Douglas and producer Joel Douglas - before they divorced in 1951.

Kirk later married Anne Buydens in 1954 and they also had two sons together, producer Peter Douglas and actor Eric Douglas, who died in 2004.

The star is known for having had relationships with a series of famous women, including Rita Hayworth, Joan Crawford and Marlene Dietrich.

Although he started out his acting career in radio, theatre and television, his friendship with Lauren led to him landing his first film role when she recommended him to director Hal Wallis for the 1946 film The Strange Love Of Martha Ivers.

He starred in a number of Westerns, including Along The Great Divide (1951) and Lonely Are The Brave (1962), as well as early Stanley Kubrick film Paths Of Glory in 1957.

Kirk has been credited with helping to put an end to the Hollywood Blacklist, where employment was denied to those working in the entertainment industry who had been accused of having Communist ties, by publicly acknowledging former Communist Party member Dalton Trumbo as the screenwriter for Spartacus.

In 1957 he won a best actor Golden Globe for Lust For Life, and in 1968 won the Cecil B DeMille Award at the Golden Globes for his outstanding contribution to the world of entertainment.

He made a Broadway adaptation of Ken Kesey's One Flew Over The Cuckoo's Nest in 1963, which he also starred in before passing on the film rights to son Michael, and has directed two Westerns - 1975´s Posse in which he starred with Bruce Dern, and the 1973 film Scalawag, where he also took a lead role.

Despite suffering a severe stroke in 1996 which affected his speech, Kirk went through years of voice therapy to get back into acting and starred in Diamonds in 1999 alongside Lauren, where he played an old fighter recovering from a stroke.

The most recent film he appeared in was 2004´s Illusion, about an ailing movie director, and in 2008 he featured in TV movie Empire State Building Murders.

As an author, he has published 10 novels and memoirs, and his blog is hosted on the Huffington Post.

Kirk has been married to Anne for 62 years and has seven grandchildren - Cameron Douglas from Michael's marriage to Diandra Luker, Carys Zeta Douglas and Dylan Michael Douglas from Michael's marriage to Catherine Zeta-Jones, and Tyler, Kelsey, Ryan and Jason Douglas by his son Peter.
