The Brooklyn Dodgers originated in 1883 as the Brooklyn Grays, joined the American Association in 1884 as the Brooklyn Atlantics, and moved to the National League in 1890, playing in Brooklyn until their famous relocation to Los Angeles in 1957—the same year their bitter rivals, the New York Giants, moved to San Francisco. Their name, shortened from "Trolley Dodgers," reflects the local residents' need to dodge the city's fast-moving trolleys, and the team later earned the affectionate nickname "Dem Bums." The club made history by signing Jackie Robinson in 1947 as the first Black player in the modern major leagues, breaking baseball's color barrier. Brooklyn itself was a baseball pioneer, hosting the first paid-admission games in 1858 and building the first enclosed ballparks; the team was founded by Charles Byrne and played at Washington Park, Eastern Park, and, from 1912, the iconic Ebbets Field. Over their 68-year tenure, the Dodgers compiled a 5,624–5,290–133 (.515) record and produced eight Hall of Famers, cementing their legacy as one of the sport's most historic franchises.
