Early life

Allende was born on 26 June 1908 in Santiago. He was the son of Salvador Allende Castro and Laura Gossens Uribe. Allende's family belonged to the Chilean upper middle class and had a long tradition of political involvement in progressive and liberal causes. His grandfather was a prominent physician and a social reformist who founded one of the first secular schools in Chile. Salvador Allende was of Basque and Belgian descent. In 1909, he moved with his family to the city of Tacna (then under Chilean administration) until he returned to his country to live in Iquique in 1916. In 1918, he studied at the National Institute of Santiago, and from 1919 to 1921, he studied at the Liceo de Valdivia. In 1922, he entered the Eduardo de la Barra school at the age of 16, studying there until 1924.

As a teenager, his main intellectual and political influence came from the shoe-maker Juan De Marchi, an Italian-born anarchist. In 1925, he attended the military service in the Cuirassier Regiment of Tacna. Allende was a talented athlete in his youth, being a member of the Everton de Viña del Mar sports club (named after the more famous English football club of the same name). In 1926, at the age of 18, he studied medicine at the University of Chile in Santiago and was elected President of the Student Center in 1927. In 1928, he entered the Grand Lodge of Chile and was elected vice president of the Federation of Students of the University of Chile in 1929. In 1930, he became the representative of the students of the School of Medicine.

During his time at medical school, Allende was influenced by Professor Max Westenhofer, a German pathologist who emphasized the social determinants of disease and social medicine. In 1931, he was expelled from the university and relegated to the north. That same year, he retook his sixth year of medical school and graduated at age 23. In 1932, he began practicing as a physician and anatomo-pathologist in the morgue of the Van Buren Hospital. He became the union leader of the Valparaíso doctors, becoming 1st Regional Secretary in Valparaíso. In 1935, at age 27, he was relegated to the city of Caldera for the second time and, in 1936, he was imprisoned in the Popular Front in Valparaíso. In 1937, he was elected Deputy of Valparaíso and Aconcagua and, in 1938, he served as Undersecretary General of the Socialist Party of Chile.

In 1933, Allende co-founded with Marmaduque Grove and others a section of the Socialist Party of Chile in Valparaíso and became its chairman. He married Hortensia Bussi with whom he had three daughters. He was a Freemason, a member of the Lodge Progreso No. 4 in Valparaíso. In 1933, he published his doctoral thesis Higiene Mental y Delincuencia (Crime and Mental Hygiene) in which he criticized Cesare Lombroso 's proposals.
