Aon History & Facts

Aon History and Facts

Aon’s fast-paced growth began in 1982 when Ryan Insurance Group merged with Combined International Corporation. In 1987, that company was introduced to Wall Street as Aon, a Gaelic word meaning “Oneness.”

Throughout the 1980s and 1990s, strategic acquisitions and organic growth fueled Aon’s expansion in the global insurance marketplace. Over the past twenty 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 that was founded in 1680. Although not all our acquisitions have this depth of history, many have been notable players in their respective fields for years:

  • Rollins Burdick Hunter
  • Reinsurancy Agency
  • Miller, Mason & Dickenson
  • Alexander & Alexander
  • Benfield Group
  • Hewitt Associates
