Our History and Facts

Aon’s fast-paced growth began in 1982 when the Ryan Insurance Group merged with Combined International Corporation.  Throughout the 1980s and 1990s, acquisitions and organic growth fueled Aon’s expansion in the global insurance marketplace.  Over the past twenty-five years, we have acquired some of the most well-known players in the insurance and consulting industries, including Hudig-Langeveldt, a provider of insurance protection for cargo ships founded in 1680.  While not all our acquisitions have this level of history behind them, many have been notable players in their respective fields for years:

  • Rollins Burdick Hunter
  • Reinsurance Agency
  • Miller, Mason & Dickenson
  • Alexander & Alexander
  • Benfield (in 2008)

Although Aon is a major leader in virtually every market it serves, size is not its primary goal.  Aon aims to be the world’s most responsive, client-focused insurance and consulting services company in the world.
