José Echegaray(何塞·埃切加赖)Unknow

He was born in Madrid on April 19, 1832.[2] His father, a doctor and institute professor, was from Aragon and his mother was from Navarra. He spent his childhood in Murcia, where he finished his elementary school education. It was there, at the Murcia Institute, where he first gained his love for math. In order to earn enough money for the Engineering School of Channels and Ports, he moved at the age of fourteen to Madrid,[3] where he enrolled at the newly created Second Teaching Institute of San Isidro. At the age of twenty, he left the Madrid School with a Civil Engineering degree, which he had obtained with the first of his promotion, and he had to move to Almeria and Granada to begin working at his first job. In his childhood he read Goethe, Homer, and Balzac, readings that alternated with those of mathematicians like Gauss, Legendre, and Lagrange. José Echegaray maintained constant activity until his death on the 14th of September, 1916 in Madrid.[2] His extensive work did not stop growing in his old age: in the final stage of his life he wrote 25 or 30 mathematical physics volumes. At the age of 83 he commented: I cannot die, because if I am going to write my mathematical physics encyclopedia, I need at least 25 more years.
