William Mills Wrigley Jr. (September 30, 1861 – January 26, 1932) was an American chewing gum industrialist. He was founder of the William Wrigley Jr. Company in 1891.
In 1909 Wrigley was elected as a non-resident member of The Lambs.
In 1916, Wrigley bought a minority stake in the Chicago Cubs baseball team as part of a group headed by Charles Weeghman, former owner of the Federal League’s Chicago Whales. Over the next four years, as Weeghman’s lunch-counter business declined, he was forced to sell much of his stock in the ball club to Wrigley. By 1918, Weeghman had sold all of his stock to Wrigley, making Wrigley the largest shareholder and principal owner, and by 1921, Wrigley was majority owner. Wrigley Field, the Cubs’ ballpark in Chicago, is named for him.
Wrigley was among other Major League Baseball club owners who were Lambs, including John T. Brush (New York Giants) and Jacob Ruppert (New York Yankees).
