George Michael Steinbrenner III, 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.
