Keystone Studios in the context of "His New Job"

Sir Charles Spencer Chaplin Jr. (16 April 1889 – 25 December 1977) was an English comic actor, filmmaker, and composer who rose to fame in the era of silent film. He became a worldwide icon through his screen persona, the Tramp, and is considered one of the film industry's most important figures. His career spanned more than 75 years, from his childhood in the Victorian era until a year before his death in 1977, and encompassed both accolade and controversy.

Chaplin's childhood in London was one of poverty and hardship. His father was absent and his mother struggled financially – he was sent to a workhouse twice before the age of nine. When he was 14, his mother was committed to a mental asylum. Chaplin began performing at an early age, touring music halls and later working as a stage actor and comedian. At 19, he was signed to the Fred Karno company, which took him to the United States. He was scouted for the film industry and began appearing in 1914 for Keystone Studios. He soon introduced and adopted the Tramp as his screen persona. He directed his own films and continued to hone his craft as he moved to Essanay Studios, where the Tramp persona was developed emotionally in The Tramp (1915). He then attracted a large fanbase and demanded more money as he moved to Mutual and First National corporations. By 1918, he was one of the world's best-paid and best-known figures.

Gloria Mae Josephine Swanson (March 27, 1899 – April 4, 1983) was an American actress. She first achieved fame acting in dozens of silent films in the 1920s and was nominated three times for the Academy Award for Best Actress, most famously for her 1950 turn in Billy Wilder's Sunset Boulevard, which earned her a Golden Globe Award.

Swanson was born in Chicago and raised in a military family that moved from base to base. Her infatuation with Essanay Studios actor Francis X. Bushman led to her aunt taking her to tour the actor's Chicago studio. The 15-year-old Swanson was offered a brief walk-on for one film and eventually a stock-players contract, beginning her life's career in front of the cameras. Swanson left school, and was soon hired to work in California for Mack Sennett's Keystone Studios comedy shorts opposite Bobby Vernon.
