Walter Weberhofer was born to Oswald Weberhofer (forester) and Dolores Quintana Pilts Gurt in San Jeronimo de Tunari, in the province of Huancayo, department of Junín, on 24 March 1923. Before graduating from Alfonso Ugarte School in 1940, he began his work as a draftsman, and achieved a position in 1942 at the Ministry of Development and Public Works. In 1946 he entered as a draftsman in the office of the Peruvian architect Enrique Seoane. This first encounter with one of the great modern architects of Peru marked the beginning of his intense search for a clean design and attention to details.
