Tadashi Kume joined Honda in 1954, eventually becoming Honda's 3rd president in 1983. He specialized in designing engines, and, along with other engineers, helped develop the fuel-effiecent CVCC. Before becoming president, Kume had a heated argument with then Honda president Soichiro Honda over using air-cooled or water-cooled engines, which led Kume to stay away from work for possibly over a month. He retired in June 1990, and was seceded by Nobuhiko Kawamoto. Kume is currently honored in the Japan Automotive Hall of Fame
