Jack Lynn Cockwell, CM, is a South African-Canadian accountant and financier, the self-made billionaire Group Chairman Emeritus (former) and Director of Brookfield Corporation (formerly Brascan/Edper), one of the world's largest asset management companies. Born in East London, South Africa, in 1941, his career is rooted in accounting and finance.

Cockwell joined Touche Ross in Cape Town in 1960 as a clerk while studying at the University of Cape Town (UCT), earning a Bachelor of Commerce and a Master of Commerce (M.Comm.) in 1966. In 1968, he was recruited by the Bronfman family to work for Edper Investments. His career is defined by his mastery of complex corporate restructuring and asset consolidation.

• Brookfield Corporation (Director & Former Group Chair): The core private asset, one of the world's largest asset management companies (investing in real estate, power, and infrastructure).
• Brascan/Edper (Former CEO & President): The foundational companies he led, orchestrating the merger to form Brookfield in 1997.
• Academic Background: He holds a Master of Commerce (M.Comm.) from UCT (1966).
• Investment Strategy: His philosophy is based on strategic asset consolidation, long-term ownership, and developing infrastructure assets (hydroelectric dams, base metal mines, and forest product mills).

Jack Cockwell's strategic genius was his role in the development and consolidation of the Edper/Brascan industrial group. He joined Brascan in 1979 and became President in 1991. In 1997, Cockwell orchestrated the merger of Edper and Brascan to form Brookfield Corporation (the first major restructuring), leading the company to focus on real estate, power generation, and infrastructure assets.

He served as President and CEO of Brookfield until 2002, after which he became Group Chairman. He is a shareholder of Partners Ltd. (a private company of former Edper managers that owns a majority voting share of Brookfield). His structural contributions include the founding of the Limberlost Forest and Wildlife Reserve (over 10,000 acres accessible to the public) and major philanthropic support for Toronto Metropolitan University (formerly Ryerson University). He is a Member of the Order of Canada (CM).

Jack Cockwell's social impact is structural, stemming from Brookfield's role in developing and managing massive infrastructure and real estate assets globally. His companies provide thousands of stable jobs in industrial and financial sectors.

His profound personal and structural contribution is the founding of the Limberlost Forest and Wildlife Reserve (a major conservation area in Huntsville, Ontario) and his financial support for Toronto Metropolitan University and the Royal Ontario Museum (where he chaired a major rebuilding project).

Jack Cockwell maintains the professional, composed style of a financier and industrialist. His attire is consistently formal and high-quality, favoring tailored suits. His aesthetic reflects stability and quiet, immense authority, befitting a founder of a global asset manager.

Residing in Toronto, Canada, his luxury is the immense security and financial reward derived from his multi-billion dollar fortune. His life is dedicated to asset management, corporate governance, and environmental conservation through his reserve and foundations.
