Early Life
John Tu was born in Chongqing, China, in 1941 during a tumultuous period in Chinese history. His father was an official in China’s Nationalist government. In 1945, the Tu family moved to Shanghai, and two years later, they relocated to Taiwan as the Chinese Civil War neared the coast.
Tu’s early education was challenging, as he described himself as a mediocre student unable to attend the best Chinese colleges. This led him to pursue opportunities abroad, first moving to Germany in 1960 to study electrical engineering.
Despite initial language barriers, Tu persevered, completing his degree at the Technische Universität Darmstadt in 1970.
Career
John Tu’s career trajectory took a significant turn after he moved to the United States in 1971. In 1982, he co-founded Camintonn Corporation with David Sun, focusing on computer memory products. They sold this company in 1986 for $6 million, but their fortunes took a hit during the 1987 stock market crash. Undeterred, Tu and Sun founded Kingston Technology that same year, which would become the cornerstone of Tu’s wealth.
Kingston Technology grew rapidly, becoming a leader in the computer memory industry. In 1996, Tu and Sun sold 80% of the company to Softbank for $1.5 billion, only to buy it back three years later for $450 million. This strategic move allowed them to retain control of the company and continue its growth.
Under Tu’s leadership as president, Kingston Technology has become the world’s largest independent manufacturer of memory products, with reported revenues of around $16.1 billion in 2022.
