Dolores Costello (September 17, 1903[1][note 1] – March 1, 1979)[2][3] was an American film actress who achieved her greatest success during the era of silent movies.

As a young adult, her career developed to the degree that in 1926, she was named a WAMPAS Baby Star,[5] and had acquired the nickname "The Goddess of the Silver Screen".

Costello spoke with a lisp and found it difficult to make the transition to talking pictures, but after two years of voice coaching she was comfortable speaking before a microphone.

Her acting career became less of a priority for her following the birth of her first child, Dolores Ethel Mae "DeeDee" Barrymore, on April 8, 1930, and she retired from the screen in 1931 to devote time to her family.

Her second child, John Drew Barrymore, was born on June 4, 1932, but the marriage proved difficult due to her husband's increasing alcoholism, and they divorced in 1935.

In the 1970s, her house was inundated in a flashflood that caused a good deal of damage to her property and memorabilia from her movie career and life with John Barrymore.
