Henry Louis "Hank" Aaron (born February 5, 1934), nicknamed "Hammer," "Hammerin' Hank," and "Bad Henry," is a retired American baseball player whose Major League Baseball (MLB) career spanned the years 1954 through 1976. Aaron is widely considered one of the greatest baseball players of all time. In 1999, editors at The Sporting News ranked Hank Aaron fifth on their list of "Greatest Baseball Players".
After playing with the Indianapolis Clowns of the Negro American League and in the minor leagues, Aaron started his major league career in 1954. In his final season, he was the only remaining and last Negro league baseball player on an active major league roster. He played 21 seasons with the Milwaukee and Atlanta Braves in the National League, and his last two years (1975–76) with the Milwaukee Brewers in the American League.
