This view shows the mausoleum of Omar Torrijos Herrera (February 13, 1929 – July 31, 1981) at the former U.S.-operated Fort Amador in Panamá City, Panamá.  Torrijos was the Panamanian military leader & dictator of Panamá, as well as the Commander of the Panamanian National Guard from 1968 to his death in 1981. Torrijos was never officially the president of Panamá, but instead held self-imposed and all-encompassing titles including "Maximum Leader of the Panamanian Revolution". Torrijos took power in a coup d'état and instituted a number of social reforms.

Torrijos is best known for negotiating the 1977 Torrijos–Carter Treaties that eventually gave Panamá full sovereignty over the Panama Canal. The two treaties guaranteed that Panamá would gain control of the Panama Canal after 1999, ending the control of the canal that the U.S. had exercised since 1903 w/ the Hay-Bunau-Varilla Treaty. On December 31, 1999, the final phase of the treaty, the US relinquished control of the Panama Canal and all areas in what had been the Panama Canal Zone.

He died in a plane crash on July 31, 1981 under mysterious circumstances.  His son Martín Torrijos was president from 2004 to 2009.
