Early Life
David Kenneth Roy Thomson was born in 1957 in Toronto, Canada, the eldest son of Kenneth Thomson, 2nd Baron Thomson of Fleet. He grew up surrounded by business and culture, attending Upper Canada College and later Selwyn College, Cambridge, where he studied history. Unlike many heirs who drift into the family business with little preparation, David spent years learning the information services industry from the ground up, working in various Thomson Corporation subsidiaries before assuming leadership. His grandfather Roy Thomson had built a media empire starting with a single radio station in northern Ontario during the Great Depression, and David inherited both the fortune and the responsibility of continuing that legacy.
