From 1961 to 2003, William K. Coors served as Chairman of the Adolph Coors Company of Golden, Colorado. The grandson of brewery founder Adolph Coors, he joined the family firm in 1939, where he pioneered the development of the recyclable aluminum can. He assumed the chairmanship and presidency of the Coors Company in 1961, shortly after his older brother, Adolph Coors III, was murdered in a bungled kidnapping attempt. Rising above this senseless tragedy, William Coors led the company through an unprecedented period of expansion, one that ultimately transformed a little known local brewery into the nation's third largest, a massive, vertically integrated business that included Coors Transportation, Coors Container (the largest single can plant in the world) and the Coors Food Products Company. He led the way in making the Coors Company energy self-sufficient, and expanded the company's program of aluminum recycling, at one point recovering and recycling as much as 85 percent of its cans, while handling a third of the nation's recycled aluminum. Even after retiring from the Board of Directors in 2003, he remained active in the company, working well into his 90s as a senior technical adviser.
