Former major league baseball player Billy Leo Williams (1938- ) was the 1961 National League Rookie of the Year, played in six All-Star games, and was named National League Player of the Year in 1972. He was voted into the National Baseball Hall of Fame in 1987. Williams spent most of his 18-year career (1959-1976) playing first base and left field for the Chicago Cubs and later for the Oakland Athletics. Known for his graceful swing of the bat, his nickname was "Sweet Swingin' Billy." Over his career, he amassed 2,711 hits, 426 home runs, batted .290, had 1,474 runs batted in (RBIs), and he once held the record for most consecutive games played, at 1,117.

Williams attended Whistler Elementary School and Mobile County Training School. In high school, he ran track and was a defensive end on the football team. By this time, he also was playing full time for the Black Bears. He was offered a football scholarship to Grambling State University in Louisiana but chose to pursue baseball instead.
In 1955, Williams's older brother Franklin signed with the Pittsburgh Pirates' minor league system (he would play minor league baseball for several years). The following year, Chicago Cubs scout Ivy Griffin travelled to Mobile to scout Hank Aaron's brother Tommie and signed Billy Williams as an amateur free agent. Two days after his high school graduation, Williams boarded a bus for Ponca City, Oklahoma, to play for the Cubs' farm team in the Class D Sooner State League. He had played as an infielder with the Black Bears, but the Cubs placed him in the outfield. His first summer on the team, he played very little and did not travel to away games. In 1957, however, he played all 126 games of the season and batted .310 with 17 homeruns and 40 doubles, although he struggled somewhat with defense.
Williams soon began rising steadily in the minor leagues. He played in the 1958 season-opener in Pueblo, Colorado, but developed a severe stomach ailment that required several weeks of recovery. He moved to San Antonio, Texas, in 1959 to play in the Double-A Texas League, splitting his time between playing first base and outfield. While there, Williams encountered overt racism for the first time. He of course had grown up in a segregated town in Alabama, but he had never before lived in a predominantly white city in the segregated South. In San Antonio, he faced discrimination in hotels and restaurants. Angered by his treatment, he left Texas to return to Alabama. Williams stayed home for a week until the Cubs scout Buck O'Neill travelled to Whistler and talked him into returning to the team. He played in San Antonio for a few weeks before being promoted to the Triple-A Texas League in Fort Worth, Texas, batting .476 in his first week. He then was called to the major leagues at the age of 21.
Williams made his major league debut with the Cubs in Chicago, Illinois, at famed Wrigley Field on August 6, 1959. On January 25, 1960, Williams married his long-time girlfriend, Shirley Williams (no relation), and the couple would raise four daughters. In 1961, Williams was installed as the Cubs' regular left-fielder. The team was not very successful but Williams was named National League Rookie of the Year, primarily for hitting 25 home runs in 146 games for a .278 batting average and for his 86 RBIs.
From 1962 until 1969, Williams averaged 162 games per year. He missed only three games in 1962 and one game in 1963, playing every game for the next seven years. He averaged 28 home runs and 95 RBIs, with a .293 batting average. On June 29, 1969, Williams played his 896th consecutive game, surpassing the number of National League games played by St. Louis Cardinals' star Stan Musial. To celebrate, the Cubs held "Billy Williams Day" at Wrigley Field, playing a double-header against the Cardinals. The Cubs held a ceremony between the games and flew Williams' mother and aunt in from Whistler.

After retiring, Williams built a house north of Sacramento, where he and his family lived near his brother Franklin. In 1978, he became a minor league instructor for the Cubs, visiting minor league clubs through the summer and spending the rest of the year with his family in California. The Cubs promoted Williams to their major league coaching staff in 1980, and he and his wife moved to Glen Ellyn, Illinois.
