Kleinwort Benson was a leading investment bank that offered a wide range of financial services from offices throughout the United Kingdom and Channel Islands. Two families, the Kleinworts and the Bensons, founded two different merchant banks in London. They merged in 1961 to create Kleinwort Benson Lonsdale, later Kleinwort Benson. Following its acquisition by Société Générale in June 2016, it was merged with SG Hambros, already a subsidiary of Société Générale, to form Kleinwort Hambros in November 2016.
