Henry Willis began broking at Lloyd’s in the 1840s and founded Henry Willis & Co. The firm merged with Faber Brothers in 1898 to form Willis, Faber & Co., and with Dumas & Wylie in 1928 to form Willis, Faber & Dumas. The company listed on the London Stock Exchange in 1976. In 1990 Willis entered the U.S. retail market through a merger with Corroon & Black to create Willis Corroon. It was taken private by KKR in 1998, adopted the Willis Group name, and relisted on the New York Stock Exchange in 2001 under the ticker WSH. Willis expanded in North America by acquiring Hilb, Rogal & Hobbs in 2008, increased its longtime stake to acquire French broker Gras Savoye in 2015, and agreed that year to purchase an 85% stake in London broker Miller. Willis launched the Willis Research Network in 2006 to link academia and industry on natural-hazard and risk science.
