Marmaduke Grove Vallejo , his name erroneously spelled Marmaduque, was a Chilean Air Force officer, political figure and member of the Government Junta of the Socialist Republic of Chile in 1932.
Grove was born in Copiap, Chile, the son of lawyer, Jos Marmaduke Grove Abalos and Ana Vallejo Burgoa. His first studies were in School Nof Copiap and later at the local Liceum. From a very young age he was interested in the army, and in 1892, was accepted to the Chilean Naval Academy. Very shortly before graduation, he participated in the socalled Stalebread rebellion, as a result of which he was expelled from the navy. That incident proved to be his turning point and from then on he declared his motto to be an undying love for the underdogs and for true justice.
