Kenneth Thomson, 2nd Baron Thomson of Fleet

Early life and entry into the family business

Kenneth Thomson was born in Toronto, Ontario, the only son of Edna Alice Irvine and Roy Thomson, who founded the Thomson media empire with radio stations and newspapers in northern Ontario. He attended Upper Canada College in Toronto and his early life included periods living in Ottawa and North Bay before his family settled in Toronto in 1937. His studies were interrupted by the Second World War, during which he served in the Royal Canadian Air Force from December 1942. Thomson was sent to England where he worked first as an instrument mechanic and later as an editor for the RCAF magazine Wings Abroad. After the war, he completed his education at St. John's College, Cambridge, earning a Master's degree in law in 1947. He returned to Canada that same year and entered the family business at the ground level, adhering to his father's philosophy of learning every aspect of the operation. His first role was as a reporter for the Timmins Daily Press in Ontario, the very newspaper his father had used as his initial acquisition in 1934. Thomson subsequently worked as a salesman for the Galt Reporter from 1948 to 1950 and then as that paper's general manager from 1950 to 1953. His thorough apprenticeship culminated in his appointment as head of Thomson Newspapers in 1953, a position he held while living in Toronto for the next thirteen years.

Leadership and expansion of the Thomson empire

Thomson's role in the international family business expanded significantly after his father purchased The Times of London in September 1966. He moved to London the following year, becoming vice-chairman and then chairman of Times Newspapers Ltd. During his three-year stay in England, he continued to acquire North American newspapers, including the Peterborough Examiner in February 1968. He returned to Toronto in 1970 and in 1971 became joint-chairman of the Thomson Organization alongside his father. Upon Roy Thomson's death in August 1976, Ken Thomson inherited the chairmanship of the Thomson Corporation and succeeded to the hereditary peerage as the 2nd Baron Thomson of Fleet. He honoured a promise to his father by using the title only in the United Kingdom, never in Canada, and he never took his seat in the House of Lords. At age fifty-three, he assumed control of a vast media empire comprising over two hundred newspaper and television holdings, which also benefited greatly from lucrative North Sea oil investments made by his father in 1971. Under his leadership, the corporation pursued major acquisitions, including the historic Hudson's Bay Company in 1979 and, through the purchase of FP Publications, The Globe and Mail in 1980. By 1979, Thomson Newspapers was the fourth most profitable newspaper chain in North America, earning $56.5 million and controlling almost one-fifth of Canada's daily newspapers in 1980.

Strategic divestitures and corporate transformation

Key divestitures included the sale of The Times and The Sunday Times to Rupert Murdoch's News Corporation in 1981 following a protracted and costly labour dispute with the newspaper's production unions. The Thomson family lost over 70 million pounds from their personal fortunes during their 14-year ownership of The Times. The North Sea oil holdings were sold in 1989, and Thomson Travel was sold in 1998. The most dramatic change began around 2000 when the company sold its entire chain of community newspapers. It refocused entirely on electronic financial data services and academic publishing, becoming one of the world's leading information companies. By 1995, revenues from subscription-based electronic information and databases had already outpaced those from printed products. In 2001, The Globe and Mail was folded into a new media partnership, Bell Globemedia, with BCE as the controlling shareholder and Thomson retaining a minority stake. The Thomson Corporation began trading on the New York Stock Exchange in 2002 under the symbol TOC. That same year, Thomson stepped down as chairman, succeeded by his elder son David, though he remained chairman of the family's private holding company, The Woodbridge Company, and stayed on the board of directors.

Kenneth Thomson became chairman of the Thomson Corporation in 1976 upon his father's death. Under his leadership, the company's value grew dramatically from $500 million US in 1976 to $20 billion by 2002. This growth was aided by strategic decisions to shift the company's focus. The company sold off its newspaper and oil holdings to concentrate on financial data services and academic publishing.

The Thomson Corporation sold its North Sea oil holdings in 1989 and its community newspapers in the early 2000s. The company then became a financial data services giant and a powerful information services company. This pivot to digital information services significantly increased the company's value. Consequently, Kenneth Thomson's personal net worth reached approximately US $19.6 billion at the time of his death in 2006.

Major business transactions under Thomson's leadership

• 1979: Acquired the Hudson's Bay Company, one of the oldest commercial corporations in the world.
• 1980: Purchased FP Publications, gaining ownership of The Globe and Mail.
• 1981: Sold The Times and The Sunday Times to Rupert Murdoch's News Corporation.
• 1989: Divested the corporation's North Sea oil holdings.
• 1996: Acquired US-based legal publisher West Publications.
• 1998: Sold the Thomson Travel group of companies.
• 2000: Completed the sale of the corporation's entire chain of community newspapers.
• 2001: The Globe and Mail was contributed to form Bell Globemedia, with BCE as controlling shareholder.

The sale of The Times in 1981 and the North Sea oil holdings in 1989 were key divestitures. The company later sold all of its community newspapers. These exits from traditional media and resources allowed the company to reposition itself. The Thomson Corporation then focused on becoming a global leader in financial data and academic publishing services.

Development of a major art collection

Parallel to his business career, Kenneth Thomson cultivated one of the most important private art collections in Canada over more than fifty years. He began collecting paintings by Cornelius Krieghoff in the late 1940s and started acquiring works by the Group of Seven in 1970. His passion for collecting grew to encompass both Canadian and European works, and he developed a close relationship with London art dealer Herman Baer after moving to England. In 1977, his collection made headlines when he invited infamous art forger Tom Keating to examine his Krieghoff paintings for authenticity, an episode reported by newspapers from The Globe and Mail to The Times of London. Keating, who was under investigation by Scotland Yard for selling fake Krieghoffs and claimed to have painted over a hundred forgeries, reported finding none of his own work in Thomson's collection. Thomson opened a private eponymous gallery in downtown Toronto in 1989 to display parts of his collection. His acquisitions were marked by record-breaking purchases, including Paul Kane's Scene in the Northwest: Portrait of John Henry Lefroy, bought for CA$5.1 million in July 2002, which set a new auction record for a Canadian painting at the time. The purchase of the Kane painting was the third time he had set an auction record for Canadian art.

The most notable acquisition of his European collection was Peter Paul Rubens' 17th-century masterpiece The Massacre of the Innocents, purchased for CA$117 million (approximately £49.5 million) also in July 2002. His European collection also included an assortment of 17th to 20th century British ship models, a series of Medieval and Baroque ivory carvings, and the 12th-century Malmesbury châsse, an ornate casket which once held the bones of a Scottish missionary. Another significant medieval acquisition was the St Thomas-a-Becket châsse, circa 1170, which he purchased at auction in 1996 for £4.18 million. By 2002, his collection included some three hundred works by Tom Thomson and the Group of Seven, a hundred and forty-five paintings by Cornelius Krieghoff, and about a hundred works by David Milne.

Historic donation to the Art Gallery of Ontario

In November 2002, Thomson announced an extraordinary philanthropic act: the donation in trust of nearly 2,000 artworks from his collection to the Art Gallery of Ontario (AGO). The collection, valued at over CA$300 million, formed the core of a new museum wing and was one of the largest cultural gifts ever made in Canada. The European collection featured medieval and Baroque ivory carvings, 17th to 20th century British ship models, and the 12th-century Malmesbury châsse. This landmark donation was instrumental in attracting architect Frank Gehry, a Toronto native, to design a major expansion and renovation of the AGO, towards which Thomson contributed an additional CA$50 million. He also provided a CA$20 million endowment for the gallery's ongoing operations, ensuring the long-term care and display of the collection he had assembled.

Key artworks and acquisitions in the Thomson Collection

Kenneth Thomson was a leading art collector throughout the latter half of the 20th century. His collection included about three hundred paintings by Tom Thomson and the Group of Seven. It also featured one hundred and forty-five scenes by Cornelius Krieghoff and many works by David Milne. Major individual masterpieces included Paul Kane's Scene in the Northwest and Peter Paul Rubens' The Massacre of the Innocents.

• Tom Thomson and the Group of Seven: Approximately 300 paintings by these foundational Canadian artists.
• Paul Kane's Scene in the Northwest: Portrait of John Henry Lefroy: Purchased for CA$5.1 million in July 2002, a record for a Canadian painting.
• Peter Paul Rubens' The Massacre of the Innocents: A 17th-century masterpiece purchased for CA$117 million in July 2002.
• The Malmesbury Châsse: A 12th-century ornate casket (reliquary) that once held saintly bones.
• The St Thomas-a-Becket Châsse: Circa 1170, purchased at auction in 1996 for £4.18 million.
• British Ship Models: An assortment of 17th to 20th century models.

The Thomson Collection features essential works by over a dozen eminent 19th to mid-20th century Canadian artists. It also includes a European collection with Medieval and Baroque ivory carvings and the 12th-century Malmesbury châsse. The collection represents a major survey of Canadian historical art. It also contains select important European decorative and fine art objects from the 17th to 20th centuries.

Personal life, family and final years

Kenneth Thomson married Nora Marilyn Lavis, a former model, in 1956. The couple had three children: David Kenneth Roy (born 1957), who succeeded him as the 3rd Baron Thomson of Fleet and chairman of the family enterprises. And Peter (born 1965). Thomson maintained a famously low public profile, preferring a quiet family life in Toronto, and was described as shy and reserved, unlike his more gregarious father. In his final years, he lived at his gated estate at 8 Castle Frank Road in the Rosedale neighbourhood. He remained chairman of The Woodbridge Company after retiring from the Thomson Corporation chairmanship in 2002. Kenneth Thomson died of an apparent heart attack at his office in Toronto on June 12, 2006, at the age of 82. He was survived by his wife, Nora, and their three children.
