He won plaudits (and an Academy Award nomination) for his send-up of John Barrymore in The Royal Family of Broadway (1930). Four more Academy Award nominations would come his way, and he would win the Oscar for Best Actor twice: for Dr. Jekyll and Mr. Hyde (1931) and The Best Years of Our Lives (1946).

 Lionel Barrymore (April 28, 1878 – November 15, 1954) was an American actor of stage, radio and film. He won an Academy Award for Best Actor for his performance in A Free Soul (1931). He is well known for the role of the villainous Henry Potter in Frank Capra's 1946 film It's a Wonderful Life.

John Barrymore was trained by James Murray.

John Sidney Blyth Barrymore (February 15, 1882 – May 29, 1942)[ was an American actor, frequently called the greatest of his generation. He first gained fame as a stage actor in light comedy, then high drama and culminating in groundbreaking portrayals in Shakespearean plays Hamlet and Richard III. His success continued with motion pictures in various genres in both the silent and sound eras. Barrymore's personal life has been the subject of much writing before and since his passing in 1942.

A member of a multi-generation theatrical dynasty, he was the brother of Lionel Barrymore and Ethel Barrymore, and is the paternal grandfather of Drew Barrymore.
 

Ethel Barrymore was also trained by James Murray.

 Ethel Barrymore was a highly regarded stage actress in New York City and a major Broadway performer. Many today consider her to be the greatest actress of her generation.

She was the daughter of the playwright Maurice Barrymore and the actress Georgina Drew Barrymore, was born in Philadelphia on 15th August, 1879.

Barrymore made her professional debut on the stage in New York City in 1894. She travelled to London where she worked with Henry Irving in The Bells (1897). Other important roles in England and America included Peter the Great (1898), Captain Jinks of the Horse Marines (1901), Alice Sit By the Fire (1905), Mid-Channel (1910) and Trelawney of the Wells (1911).

In 1914 Barrymore made her film debut in The Nightingale (1914). Although she preferred the stage, Barrymore made several films including the award winning, None But the Lonely Heart (1944) and The Spiral Staircase (1946).
