He was America's boldest and most spectacular entrepreneur. For three decades - from the 1930s to the 1960s - Henry J. Kaiser blazed across the skies like no other industrialist ever did before or since. Boldly plunging into an almost unbelievable diversity of business ventures (including the nation's first - and still largest and most successful - HMO), he personified all that we boast about when we praise the advantages of our free enterprise system. By 1967, the year he died, the companies he founded were operating 242 plants and mines in the United States and around the world. It could accurately be said the sun never set on his operations.
