Coronel Juan de Dios Rawson, whose father came from Massachusetts, fought in several battles during Argentina’s early years of organization, including the Guerra de la Triple Alianza. He was also the half brother of Dr. Guillermo Rawson. But his great-grandson, Arturo Rawson, became President of Argentina… for only 72 hours.
Rawson had a long career in the military & rose to the rank of General after several decades of service. As commanding officer of the cavalry, he possessed the troops needed to stage a successful coup d’etat already planned by the GOU (Grupo de Oficiales Unidos) in 1943. This secret, informal collection of officers aimed to end the Década Infame where electoral fraud kept the same people in power year after year.
On 04 Jun 1943, Rawson marched 10,000 soldiers into Buenos Aires & took control of the country. While naming fellow officers to government positions & before he was sworn in as de facto President, the GOU realized they had made a mistake in asking Rawson for help. He supported the Allies in World War II while the GOU thought Argentina should remain neutral. Juan Domingo Perón, along with other GOU members, forced Rawson to resign & General Pedro Ramírez took his place.
For a brief period Rawson served as ambassador to Brazil. He also supported an attempted coup to overthrow Perón’s government in 1951. Rawson died of a heart attack the following year & did not live to see the eventual ousting of Perón in 1955.
