David Samanez Ocampo (4 November 1865 – 13 July 1947)1, the son of José Samanez, served as Interim President of Peru, officially as the President of the Southern Junta, during the transitional period of March to December 1931.
He oversaw changes to the electoral statutes that effectively brought the vote to the masses, leading to the critical – if highly controversial – presidential election of December 1931, when Sánchez Cerro defeated Victor Raúl Haya de la Torre.
Instrumental in his appointment was his reputation and high prestige among politicians of all factions.
