Who owns Marsh McLennan Company?

Marsh McLennan, a global professional services firm, is publicly traded on the New York Stock Exchange under the ticker symbol MMC. This means its ownership is distributed among its shareholders. As of 2024, the company reported annual revenues exceeding $24.5 billion and employs over 90,000 colleagues across 130 countries.

The foundation of Marsh McLennan's ownership traces back to a pivotal partnership established by Henry W. Marsh and Donald R. McLennan. Marsh, who left Harvard College in 1885, began his career in the insurance industry, eventually co-owning Marsh, Ulmann and Company. McLennan, having started his own agency, joined forces with Marsh in 1906, creating Marsh & McLennan.

Early Partnership

Henry W. Marsh and Donald R. McLennan formed a partnership that laid the groundwork for the company. Their combined expertise in insurance agency operations was crucial in the early stages.

Merger and Growth

Henry W. Marsh was a key figure in developing modern self-insurance and risk management strategies. His advice to major corporations highlighted the evolving landscape of corporate risk.
