Cesar Chavez (born César Estrada Chávez, ] ; March 31, 1927 – April 23, 1993) was an American labor leader and civil rights activist who, with Dolores Huerta, co-founded the National Farm Workers Association (later the United Farm Workers union, UFW) in 1962.
 Originally a Mexican American farm worker, Chavez became the best known Latino American civil rights activist, and was strongly promoted by the American labor movement, which was eager to enroll Hispanic members.
 His public-relations approach to unionism and aggressive but nonviolent tactics made the farm workers' struggle a moral cause with nationwide support.
 By the late 1970s, his tactics had forced growers to recognize the UFW as the bargaining agent for 50,000 field workers in California and Florida.
 However, by the mid-1980s membership in the UFW had dwindled to around 15,000.

 Morgan was also one of the founders and leading figures of the United Labor Party, an Illinois political party which elected 7 of its members to the Illinois State Assembly and another to the Illinois State Senate in the election of 1886.

 One high-ranking Chicago Teamsters leader noted in 1954, "He is the mob.
 When he opens his mouth, it's the syndicate talking."
 Glimco was active in the International Brotherhood of Teamsters (IBT) and a close associate of Teamsters president Jimmy Hoffa.
 He was a capo in the Chicago Outfit, an organized crime syndicate, and oversaw the syndicate's labor racketeering efforts.
 He worked closely with Tony "Joe Batters" Accardo, who led the Chicago Outfit from 1943 to 1957, and Sam "Momo" Giancana, who led the syndicate from 1957 to 1966.
 A United States Senate committee once claimed that Glimco ran "the nation's most corrupt union."
