Henry "Hank" Louis Aaron, nicknamed "Hammer" or "Hammerin' Hank", was an American professional baseball right fielder and designated hitter who played 23 seasons in Major League Baseball (MLB), from 1954 through 1976. Considered one of the greatest baseball players in history, he spent 21 seasons with the Milwaukee / Atlanta Braves in the National League (NL) and two seasons with the Milwaukee Brewers in the American League (AL). At the time of his retirement, Aaron held most of the game's key career power-hitting records. He broke the long-standing MLB record for career home runs held by Babe Ruth and remained the career leader for 33 years, until Barry Bonds surpassed his famous total of 755 in 2007. He hit 24 or more home runs every year from 1955 through 1973 and is one of only two players to hit 30 or more home runs in a season at least fifteen times.
