José Rius

José Rius y Casas (born March 21, 1867 in Barcelona , † December 18, 1940 in Saragossa ) was a Spanish mathematician .

Rius graduated from the University of Barcelona in 1887 and received his doctorate from the Complutense University of Madrid (Universidad Central) in 1889 (at that time the only Spanish university that awarded doctoral degrees). In the same year he became an assistant at the observatory in Madrid and from 1890 was an unpaid lecturer at the Universidad Central. But he taught mathematics at the School of Arts and Crafts (Escuela de Artes y Oficios) and was its director from 1892. In 1898 he became professor of analysis in Granada and in the same year, after a competition, changed to a chair at the University of Zaragoza . In 1937 he retired.

With Zoel García de Galdeano and Leonardo Torres Quevedo he founded the mathematics journal Revista Trimestral de Matemáticas , which was published from 1901 to 1906. Before that, there were only El Progreso Matemático by Galdeano (1891 to 1900) and the Archivo de Matematicas Puras y Aplicadas (1898 to 1899 in Valencia, edited by Luis Gonzalo Gascó) as specialist mathematics journals in Spain.

In 1904 he received the Zaragoza gold medal and was twice on its city council. From 1892 he was a member of the Royal Academy of Sciences in Barcelona. He took part in the International Congress of Mathematicians in Paris in 1900 (with Galdeano and Quevedo).

From 1891 he was married to Carmen Gelabert y Solá, with whom he had eleven children.
