About George Steinbrenner
George Michael Steinbrenner III (July 4, 1930 – July 13, 2010), nicknamed "the Boss", was an American businessman who was the principal owner and managing partner of Major League Baseball's New York Yankees from 1973 until his death in 2010. He was the longest-serving owner in club history, and the Yankees won seven World Series championships and 11 American League pennants under his ownership. His outspokenness and role in driving up player salaries made him one of the sport's most controversial figures. Steinbrenner was also involved in the Great Lakes and Gulf Coast shipping industry. Originally known as a very hands-on owner, Steinbrenner earned the nickname "the Boss". He had a tendency to meddle in daily on-field decisions, and to hire and fire (and sometimes re-hire) managers. Former Yankees manager Dallas Green gave him the derisive nickname "Manager George". However, from the early 1990s onward, he mostly left the Yankees in the hands of the baseball operations staff and rarely interfered. He officially retired from day-to-day control of the team in 2008. He died after suffering a heart attack in his Tampa home on the morning of July 13, 2010, the day of the 81st All-Star Game. The Yankees are now owned by Yankee Global Enterprises, for which Steinbrenner's four children have served as general partners. He was an accomplished hurdler on the varsity track and field team, and served as sports editor of The Williams Record, played piano in the band, and played halfback on the football team in his senior year. The Buckeyes were undefeated national champions that year, and won the Rose Bowl.
