Short answers, pulled from the story.
Carl Laemmle was a German-American film producer who co-founded Universal Pictures and served as its owner until 1934. Born on the 17th of January 1867 in Laupheim, Kingdom of Württemberg, he immigrated to the United States in 1884 and built one of Hollywood's foundational studios.
Carl Laemmle opened Universal Studios Hollywood on the 15th of March 1915. The facility was built on a 230-acre converted farm in the San Fernando Valley, just over the Cahuenga Pass from Hollywood, and was at the time the world's largest motion picture production facility.
Laemmle is best remembered for The Hunchback of Notre Dame (1923) and The Phantom of the Opera (1925), both starring Lon Chaney Sr., as well as The Man Who Laughs (1928) and early sound horror films including Dracula and Frankenstein (both 1931). The studio also received the Academy Award for Outstanding Production for All Quiet on the Western Front (1930), produced by his son Carl Laemmle Jr.
Laemmle lost control of Universal Pictures in 1936 after he sponsored filmmaker James Cruze to direct the western Sutter's Gold, giving him unlimited creative freedom. Cruze overspent dramatically, and the film was a notorious box office failure. A consortium of investors responded with a hostile takeover, removing both Laemmle and his son Carl Jr. from the studio.
In the 1930s, Laemmle sponsored hundreds of Jews from Laupheim and the Württemberg region to emigrate from Nazi Germany to the United States, personally paying both emigration and immigration fees. He contacted members of the House of Representatives and Secretary of State Cordell Hull to facilitate entry, and also attempted to intervene for refugees aboard a ship turned away from Havana in 1939.
Laemmle himself explained the pronunciation to The Literary Digest in 1936, saying the name means "little lamb" and should be pronounced "as if it were spelled 'lem-lee.'"
