Soichiro Honda The founder of Honda, Soichiro Honda was a mechanical engineer with a passion for motorcycle and automobile racing. Honda started his company in 1946 by building motorized bicycles with small, war-surplus engines. Honda would grow to become the world's leading manufacturer of motorcycles and later one of the leading automakers. Following its founder's lead, Honda has always been a leader in technology, especially in the area of engine development. Soichiro Honda was described as a maverick(特立独行的人) in a nation of conformists. He made it a point to wear loud suits and wildly colored shirts. An inventor by nature who often joined the work on the floors of his factories and research laboratories, Honda developed engines that transformed the motorcycle into a worldwide means of transportation. Born in 1906, Honda grew up in the town of Tenryu, Japan. The eldest son of a blacksmith who repaired bicycles, the young Soichiro had only an elementary school education when, in his teens, he left home to seek his fortune in Tokyo. An auto repair company hired him in 1922, but for a year he was forced to serve as a baby-sitter for the auto shop's owner and his wife. While employed at the auto shop, however, Honda built his own racing car using an old aircraft engine and handmade parts and participated in racing. His racing career was short lived, however. He suffered serious injuries in a 1936 crash. By 1937, Honda had recovered from his injuries. He established his own company, manufacturing piston rings, but he found that he lacked a basic knowledge of casting. To obtain it, he enrolled in a technical high school, applying theories as he learned them in the classrooms to his own factory. But he did not bother to take examinations at the school. Informed that he would not be graduated, Honda commented that a diploma was 'worth less than a movie theater ticket. A ticket guarantees that you can get into the theater. But a diploma doesn't guarantee that you can make a living.' Honda's burgeoning company mass produced metal propellers during WW Ⅱ, replacing wooden ones. Allied bombing and an earthquake destroyed most of his factory and he sold what was left to Toyota in 1945. In 1946, he established the Honda Technical Research Institute to motorize bicycles with small, war-surplus engines. These bikes became very popular in Japan. The institute soon began making engines. Renamed Honda Motor in 1948, the company began manufacturing motorcycles. Business executive Takeo Fujisawa was hired to manage the company while Honda focused on engineering. In 1951, Honda brought out the Dream Type E motorcycle, which proved an immediate success thanks to Honda's innovative overhead valve design, The smaller F-type cub (1952) accounted for 70% of Japan's motorcycle production by the end of that year. A public offering and support from Mitsubishi Bank allowed Honda to expand and begin exporting. The versatile C100 Super Cub, released in 1958, became an international bestseller. In 1959, the American Honda Motor was founded and soon began using the slogan, 'You meet the nicest people on a Honda,' to offset the stereotype of motorcyclists during that period. Though the small bikes were dismissed by the dominant American and British manufacturers of the time, the inexpensive imports brought new riders into motorcycling and changed the industry forever in the United States. Ever the racing enthusiast, Honda began entering his company's motorcycles in domestic Japanese races during the 1950s. In the mid-1950s, Honda declared that his company would someday win world championship events--a declaration that seemed unrealistic at the time. In June 1959, the Honda racing team brought their first motorbike to compete in the Isle of Man Tourist Trophy race, then the world's most popular motorcycleA．YB．NC．NG
