For many years the Salomon family have had a significant interest in financial services.
In the early 1950's Sir Walter Salomon gained a controlling interest in merchant bank Rea Brothers. In the mid 1980's, shortly before Sir Walter's death, the family established Finsbury Asset Management (FAM). William Salomon, with his extensive knowledge of private client and strategic fund investment business and assisted by his brother-in-law Anthony Townsend, was responsible for developing FAM and the Finsbury range of funds which was based on the concept of early recognition of key investment trends, such as life sciences and technology, and appointing specialist managers. In 1995 FAM was taken over by Rea Brothers with William eventually becoming Chairman of the bank.
In 1999 with greater competition and ever more regulation the family felt it appropriate to divest themselves from Rea Brothers and the bank was taken over by Close Brothers Group where William remained having been appointed Deputy Chairman of the Investment Division. By this time William had already established Hanseatic Asset Management LBG and from 2000 the Hanseatic Group started its development.
