Diane Keaton, born Diane Hall on January 5, 1946, in Los Angeles, California, began her acting career in an inspiring family environment.

Her mother, Dorothy Deanne (née Keaton), was a homemaker and amateur photographer, while her father, John Newton Ignatius "Jack" Hall, worked as a real estate broker and civil engineer.

Her initial inspiration to become an actress came after her mother won the "Mrs. Los Angeles" pageant for housewives.

To hone her talent, Diane Keaton studied acting at Santa Ana College in California and later at the Neighborhood Playhouse in New York.

She decided to use her mother's last name, Keaton, as her stage name to avoid confusion with another Diane Hall, who was already registered with the Screen Actors Guild.

Her stage career began with an appearance in the 1968 Broadway production of the musical 'Hair'.

A year later, she also starred in Woody Allen's comedy-drama 'Play It Again, Sam', which earned her a Tony Award nomination for Best Featured Actress in a Play.

Diane Keaton's screen debut came with a small role in the 1970 film 'Lovers and Other Strangers'.

However, her fame began with her breakout role as Kay Adams in Francis Ford Coppola's epic film 'The Godfather' (1972).

The role was so ingrained in her, that she reprised the role in its sequels, 'Part II' (1974) and 'Part III' (1990).

In 1977, Diane Keaton reached the pinnacle of her career by winning the Academy Award for Best Actress for her performance in the romantic comedy-drama 'Annie Hall'.

Throughout her career spanning more than five decades, Diane Keaton has received numerous prestigious accolades.

These include one Academy Award, one BAFTA Award, and two Golden Globe Awards, as well as nominations for two Emmy Awards and one Tony Award.

In addition to her screen work, Diane Keaton also showcased her talents on television.

She portrayed Amelia Earhart in the TNT film *Amelia Earhart: The Final Flight* (1994), which earned her nominations for a Primetime Emmy Award, a Golden Globe Award, and a Screen Actors Guild Award.

Beyond acting, Diane Keaton was also known as a fashion icon with her unique and bold fashion style.

She was also a prolific author, having published four books, including her memoir 'Then Again' in 2011.

In her personal life, Diane Keaton never married.

However, she was a loving mother to her two adopted children: a daughter named Dexter Keaton, born in 1995, and a son named Duke Keaton, born in 2000.
