Marsh McLennan Companies (MMC) is a professional services firm that’s behind some of today’s major insurance and consulting players, including Marsh, Guy Carpenter, Mercer, and Oliver Wyman.
The company was founded by Henry W. Marsh and Donald R. McLennan, who merged their two firms in 1904 to create the largest insurance agency in the world. Before the merger, Marsh had seen an opportunity for insurance brokers to distribute risks across firms following the Great Fire of 1871, which wiped out many insurers.
MMC is the parent company of Marsh Inc., the world’s leading risk and insurance firm, which operates in more than 100 countries; Putnam Investments, Inc., one of the largest U.S. money management firms; and Mercer Consulting Group, serving the areas of strategic and operational human resource consulting and implementation and ranking among the largest firms of its kind in the world.
Today, Marsh is an insurance broking and risk management giant, with offices around the world. Meanwhile, Guy Carpenter offers reinsurance broking expertise as well as strategic advisory services and analytics. Oliver Wyman is a global management consulting firm and Mercer is a human resources consulting firm.
