Santiago Antúnez de Mayolo

Peruvian engineer, physicist and mathematician (1887-1967)

A gold medal from President José Pardo marked the academic beginning of Santiago Antúnez de Mayolo in 1906, shortly before he left Peru to pursue international studies. Spanning the fields of engineering, physics, and mathematics, his career concentrated on foundational research and infrastructure development within his home country while contributing to the global understanding of atomic structure.

Academic Foundation and International Training

Born in 1887 in the Huacllan District, Antúnez de Mayolo attended the Colegio Nacional de la Libertad in Huaraz and the College of Our Lady of Guadalupe in Lima. By 1905, he gained admission to the Mathematical Sciences faculty at the National University of San Marcos. Following his early distinctions in Lima, he moved to France to earn a degree in Electrical Engineering from the University of Grenoble. He later expanded his technical background through further study at Columbia University.

Scientific Theoretical Contributions

Antúnez de Mayolo presented 'Hipótesis sobre la constitución de la materia' at the Third Pan-American Scientific Congress in Lima. In this work, he proposed the existence of a neutral element within the atom, a concept validated eight years later by James Chadwick. He subsequently published 'Los tres elementos constitutivos de la materia' in 1934, where he predicted the existence of the positron. David Anderson later identified this particle, earning a Nobel Prize for the discovery in 1936.

Engineering and National Service

Returning to Peru in 1912, he held a professorship at the National University of San Marcos. Beyond his academic duties, he traveled across the country to survey geography and terrain suitable for the construction of hydroelectric central power stations. His professional impact was recognized through national accolades, including the Palmas Magisteriales and his appointment as a Commander of the Order of the Sun of Peru.
