Blas Cabrera Felipe

Blas Cabrera y Felipe (1878 in Arrecife, Lanzarote – August 1, 1945 in México DF) was a Spanish physicist.

Cabrera received his baccalaureate in La Laguna (Tenerife, Spain). He then moved to Madrid where he began studying law, following family tradition. He met at that time Santiago Ramón y Cajal, who convinced him to abandon law and study science. He graduated from the Universidad Central de Madrid (present day Complutense University of Madrid) in Physics and Mathematics, earning a doctorate in Physics in 1901 with thesis Sobre la Variación Diurna de la Componente Horizontal del Viento written under the supervision of Santiago Ramón y Cajal.

He was an experimental physicist, and developed his interests mostly in the field of magnetic properties of matter, achieving a prominent position among the physicists of his era. In 1903 he participated in the foundation of the Spanish Society of Physics and Chemistry and the annals of that society. In 1905, he obtained the chair of Electricity and Magnetism in the Universidad Central. He married María Sánchez Real in 1909. In 1910, the Junta de Ampliación de Estudios created the Laboratorio de Investigaciones Físicas, of which Cabrera was appointed as director. The Laboratory had five lines of investigation: magnetochemistry, physical chemistry, electrochemistry, electroanalysis and spectroscopy, and contributed greatly to the research and development of physics in Spain. With a grant from the Junta de Ampliación de Estudios (1912), Cabrera visited several European research centers including the Physics Laboratory of the Politechnic of Zurich (directed by Peter Weiss), in which he carried out experiments in magnetochemistry. He also visited the physics laboratories of the universities of Geneva and Heidelberg, and the International Bureau of Weights and Measures in Paris.
