Time's December 22, 1930, issue announced that the three-way merger featured 11 Yale graduates among 16 founding partners.
Eight of the partners listed above, except for Moreau Delano and Thatcher Brown, were Skull and Bones members.

In 1930s the company acted as a US base for the German industrialist, Fritz Thyssen, who helped finance Adolf Hitler.

After the passage of the Glass-Steagall Act, the partners decided to focus on commercial banking, becoming a private bank, and spin its securities marketing and underwriting off into Harriman, Ripley and Company which eventually evolved into Drexel Burnham Lambert via mergers.

Harriman, a partner in the firm, was the ambassador and statesman responsible for the relationship between Winston Churchill and Franklin Roosevelt during World War II.
Some historical records of Brown Brothers Harriman and its precursor companies are housed in the manuscript collections at the New-York Historical Society.
