Born in Saint John, New Brunswick, Arthur Nesbitt first worked as a dry goods salesman, peddling products to area merchants.
[1] Nesbitt was hired by British newspaper magnate Max Aitken, better known as Lord Beaverbrook, to work for his Royal Securities Corporation stock brokerage.
In 1906, after undergoing training in London, England, Aitken sent Nesbitt to open a Royal Securities office in Montreal, Quebec, the then financial center of Canada.
The business provided financing for the burgeoning mining and natural resource industries and underwrote stock and bond issues for the many new electric power generating companies that were springing up across the country.
[1] Arthur Nesbitt supported various benevolent causes, including a gift to the hospital in his New Brunswick hometown to build a tuberculosis sanitarium for children, in memory of his parents.
