Humphrey Toomey (1900-1974) graduated from the Naval Academy in 1922 as an aeronautical engineer. Following his training and service as a naval aviator, Toomey resigned from the Navy in 1929 to pilot a Sikorsky S-38 on a flight from Bridgeport, Connecticut to Buenos Aires. This flight laid the groundwork for the commercial routes to South America for the New York, Rio and Buenos Aires Line (NYRBA). Toomey was a pilot for NYRBA from 1929 until it was acquired in 1930 by Pan American Airways (PAA). Toomey then worked for PAA as Chief Pilot and Operations Manager for their Brazil-Argentina sector. In this capacity Toomey established a series of airports for PAA and organized the Brazilian national airline, PAA do Brazil. In 1933, Toomey made the first official survey flight up the Amazon River, which won him membership in the New York Explorers Club. During World War II he managed the Military Contact Division of PAA, and from 1946 to 1952 he served as Manager of the Latin American Division in Miami , Florida. In 1952, Toomey returned to Rio de Janeiro as PAA Vice President for Brazil, Argentina, Uruguay and Paraguay. Toomey retired from PAA in 1962 and was the recipient of many awards, including the Brazilian "Ordem Nacional do Cruzeiro do Sul."
