History
Founding, 1800s After immigrating to Baltimore in 1800 and building a successful linen trading business, Alexander Brown and his four sons co-founded Alex. Brown & Sons. a "To him were born in Ballymena, four sons, William, George, John Alexander and James." — Pg. 116, ¶ 2 b "The family came to America in 1800, settling in Baltimore, where, after a prosperous career as a linen merchant, Mr. Brown founded the bank of Alex. Brown & Sons, in partnership with his four sons. He died April 6, 1834." — Pg. 116, ¶ 2 c "established the houses of Brown, Shipley & Co., in England a "the oldest continuously operating investment bank in America, according to experts. Founded in 1800 as Alex. Brown & Sons" — ¶ 17 In 1818, one son, John Alexander Brown, traveled to Philadelphia to establish John A. Brown and Co. a "John A. Brown travels to Philadelphia and establishes John A. Brown & Co. ... John A. Brown's historic Philadelphia house also serves as the founding date for the future Brown Brothers Harriman & Co." — Pg. 1, ¶ 8 In 1825, another son, James Brown, established Brown Bros. & Co. a "Baltimore in 1800 and opened a dry goods business with which his four sons became associated." b "One son, John (1788–1872), opened a branch in Philadelphia in 1818" c "Another son, James (1791–1877) established Brown Brothers & Co. in New York City in 1825 and eventually absorbed the other branches." d "In addition, Brown Brothers & Co. was associated with the English firm of Brown, Shipley & Co., which was run by another brother, William Brown (1784–1864)." on Pine Street in Lower Manhattan and relocated to Wall Street in 1833. This firm eventually acquired all other Brown branches in the U.S.
Following the panic of 1837, Brown Brothers withdrew from most of its lending business. Two of the brothers, John and George, sold their shares in the company to the other two brothers, William and James. During the recovery from this economic turmoil, they chose to focus solely on currency exchange and international trade.
Another son, William Brown, had established William Brown & Co. in England in 1810, which was renamed Brown, Shipley & Co. in 1839 and became a separate entity in 1918.a "linen merchant Alexander Brown emigrated to the United States in 1800" — ¶ 1 b "In 1810, Alexander's eldest son William returned to England and established the trading firm William Brown & Co. in Liverpool. This became Brown Shipley & Co. in 1839 and relocated to London. It separated from Brown Brothers as a distinct business entity in 1918." — ¶ 1
Merger, 1900s
On January 2, 1931, Brown Brothers & Co. merged with two other business entities, Harriman Brothers & Company, a private bank started with railway money, and W. A. Harriman & Co. to form Brown Brothers Harriman & Co. Founding partners included: Prescott Bush, E. Roland Harriman, W. Averell Harriman, Robert A. Lovett, and Knight Woolley.
Time December 22, 1930, issue announced that the three-way merger featured 12 Yale graduates among 17 founding partners, of which eight had been Yale Skull and Bones members.
After the passage of the Glass-Steagall Act in 1932, the partners decided to focus on commercial banking, become 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.
W. Averell Harriman, the founding partner in the firm, left the leadership to his younger brother, E. Roland Harriman, and became a diplomat in World War I and World War II. W. Averell Harriman 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.
