In 1928, he became Governor of the
Federal Reserve Bank of Atlanta. He succeeded the longtime governor,
Max Wellborn, who was also his daughter's father-in-law. When the
Wall Street Crash of 1929 happened, he and two cashiers rushed to
Nashville, Tennessee, to supply currency and credit to banks in the city and surrounding region. The situation worsened with other cities in the region experiencing
bank runs. Black kept his district afloat by rushing large quantities of cash to banks that were experiencing runs and extending credit to any bank that could offer any asset of value. He kept this policy active through the
Great Depression into 1933. He, along with
George L. Harrison, the governor of the
Federal Reserve Bank of New York, recommended
open market purchases to increase reserves. His insistence on expansionist policies led to the President appointing Black to the
Federal Reserve Board in 1933. == Personal life ==
