Hiroshi Yamauchi was a Japanese businessman. He was the third president of Nintendo, joining the company in 1949 until stepping down on May 31, 2002, to be succeeded by Satoru Iwata. During his 53-year tenure, Yamauchi transformed Nintendo from a small-scale hanafuda card-making company that had been active solely in Japan, into a multibillion-dollar video game publisher and global conglomerate that it is today. As of April 2013, Forbes estimated Yamauchi’s net worth at $2.1 billion; he was the 13th richest person in Japan and the 491st richest in the world. In 2008, Yamauchi was Japan’s wealthiest person with a fortune at that time estimated at $7.8 billion. At the time of his death, Yamauchi was the largest shareholder at Nintendo.
