Dallas grew Revere Copper & Brass, a merger of six brass and copper companies, into a $100 million annual business. Dallas, keen on communication, wrote a monthly letter, which was sent to the homes of all Revere employees. Following World War II, Dallas successfully persuaded Congress to repeal the four-cent a pound excise tax on imported copper. To increase Revere’s reach internationally, Dallas acquired a half-interest in a brass and copper manufacturing plant in Sao Paulo, Brazil.
