After taking over from the French, the US oversaw the successful opening of the Panama Canal on August 15, 1914. 3 Chief Engineers - Wallace, Stevens and Goethals overcame several odds, both engineering and manpower related, during their respective tenures, to see the Canal through to completion. Equally commendable was the contribution of Chief Sanitation Officer, William Gorgas in defeating the scourge of Yellow Fever and Malaria, within the Canal Zone.
