Henry John Kaiser was an American industrialist who became known for his shipbuilding and construction projects, then later for his involvement in fostering modern American health care. Prior to World War II, Kaiser was involved in the construction industry; his company was one of those that built the Hoover Dam. He established the Kaiser Shipyards, which built Liberty ships during World War II, after which he formed Kaiser Aluminum and Kaiser Steel. Kaiser organized Kaiser Permanente health care for his workers and their families. He led Kaiser-Frazer followed by Kaiser Motors, automobile companies known for the safety of their designs. Kaiser was involved in large construction projects such as civic centers and dams, and invested in real estate, later moving into television broadcasting. With his wealth, he established the Kaiser Family Foundation, a nonprofit, non-partisan, charitable organization.
