Néstor Guillén

Néstor Guillén Olmos (28 January 1890 – 12 March 1966) was a Bolivian judge, lawyer, and politician who served as the 40th president of Bolivia from July to August 1946.

Background and earlier career Born in La Paz, Guillén studied law and rose to become the dean of the Superior District Court of La Paz.

President of Bolivia Néstor Guillén served as President of Bolivia for 27 days between July and August 1946, following the overthrow and assassination of President Gualberto Villarroel (1943–46). Upon the death of Villarroel, the alliance of forces that had toppled him needed a reliable and impartial caretaker (given the mood of the citizenry, which had just shown what it was capable of during the revolt) to guide the country to elections. They settled on the head of the La Paz Court of Appeals, Tomás Monje Gutiérrez, who was ill at the time. Thus, Guillén filled in for him for fewer than four weeks, whereupon Monje was sworn in as president. The old oligarchy was established again but, not long after, would fall only a few years later.

Later career and death Guillén then returned to his judgeship and died on 12 March 1966 in La Paz.
