Early Education and European Influence
Born in Logroño, Spain, Rey Pastor began his scientific journey in Vitoria before moving to the University of Saragossa. He was deeply influenced by Zoel García de Galdeano, a professor of Analytical Geometry and Calculus, and graduated with honors in 1908. He subsequently earned his doctorate from the Complutense University of Madrid in 1909 under the guidance of Eduardo Torroja Caballé.
Between 1911 and 1914, Rey Pastor expanded his horizons in Germany, studying at the University of Berlin and the University of Göttingen. During this pivotal period, he worked under the supervision of the renowned Felix Klein, as well as Hermann Schwarz, Friedrich Hermann Schottky, and Ferdinand Georg Frobenius. He was particularly impressed by Schwarz's teaching methods and his lectures on synthetic geometry (a form of geometry that does not use coordinates) and analytic functions.

Modernizing Spanish Mathematics
Upon returning to Spain, Rey Pastor sought to implement the research-driven models he had observed in Germany. He proposed the creation of a mathematics seminar to inspire research among students, leading the Junta para Ampliación de Estudios (JAE) to establish the Mathematics Laboratory and Seminar in 1915.
This laboratory was a landmark institution designed to break the individualism and isolation of Spanish mathematicians. Over time, the facility moved through various locations—including the basement of the National Library—before eventually becoming part of the Consejo Superior de Investigaciones Científicas (CSIC) and being renamed the Instituto Jorge Juan de Matemáticas in 1939.
Beyond institutional leadership, Rey Pastor authored several advanced mathematics textbooks that became fundamental resources throughout the Iberian world, effectively modernizing how the subject was taught and researched in the region.
Influence in Argentina and Global Reach
In 1921, Rey Pastor settled permanently in Argentina, where he replicated his success in building academic infrastructure. By the mid-1930s, he was directing a significant group of research students in Buenos Aires, effectively creating two parallel schools of mathematical thought—one in Spain and one in Argentina—that collaborated across the Atlantic.
His contributions to Argentine science were solidified in 1936 when he played an instrumental role in founding the Argentine Mathematical Union, serving as the director of its journal until 1940.
Despite his residence in Argentina, he remained deeply connected to Spain. In 1951, he was appointed director of the Instituto Jorge Juan de Matemáticas. His later goals included establishing an Institute of Applied Mathematics and a university seminar dedicated to the history of science.
Academic Honors and Legacy
Rey Pastor's intellectual breadth led him to the Real Academia Española in 1954, where he delivered a notable acceptance speech on the algebra of language. He had previously been admitted to the Academy of Sciences in Madrid (1920) and Buenos Aires (1932).

Rey Pastor's legacy is preserved through various memorials, including a Spanish postage stamp issued in 2000 and the Calle Matematicos Rey Pastor y Castro in Seville. While a lunar crater (Faraday G) was proposed to be named after him, the designation was not officially adopted by the International Astronomical Union.
