What is the history of Marsh & McLennan Companies Inc.?

Asked 2 years ago
Marsh & McLennan Companies Inc. has a rich history that dates back to the early twentieth century. The firm was founded in 1871 by Henry Marsh and Donald McLennan in New York City, initially focusing on providing insurance brokerage services. The company quickly established itself as a leader in the insurance sector, and by the early 1900s, it had expanded its offerings to include risk management and consulting services. Throughout the twentieth century, Marsh & McLennan experienced substantial growth, both organically and through acquisitions. In the 1950s and 1960s, the company enhanced its global presence by acquiring various firms, thus bolstering its capabilities and market reach. One of the significant landmark moments in the company's history was the listing of Marsh & McLennan on the New York Stock Exchange in 2001. In the wake of the September 11 attacks in 2001, the company faced significant challenges, but it adapted successfully by restructuring and diversifying its services. Today, Marsh & McLennan operates through several key divisions, including Marsh, Guy Carpenter, Mercer, and Oliver Wyman, offering a wide range of services in risk, strategy, and people consulting.
