(Per Wikipedia) The Wrigley Building was constructed between 1920 and 1924. When work was begun, the Michigan Ave Bridge traversing the Chicago River due south of the building site was still under construction. It was chosen by William Wrigley, Jr for the headquarters of his chewing gum empire. In 1921, he became the principal owner of the Chicago Cubs and their playing field was renamed for him in 1926. His was the first office-building in Chicago to use air-conditioning.
Lesser known is Mr. Wrigley’s role as the developer of (Santa) Catalina Island off the coast of Long Beach, CA. In 1919, he bought a controlling stake in the Santa Catalina Island Company which also gave him ownership of the land itself. He is credited with modernizing the island’s infrastructure, adding a hotel and casino that opened in May 1929 (of note, the Great Crash of ’29 happened in Sept/Oct of that year). In keeping with the paradox of modern capitalism, he established a quarry and tile factory there while also initiating a tradition of island conservation. His son Philip K. Wrigley carried on that spirit with the Catalina Island Conservancy in 1972. It is rumored that he also founded the vaunted Catalina Wine Mixer.
