Early life

Vallés was born 4 November 1925 in Logroño, Spain, to an engineer. When he was ten, his father died of Vincent's angina. Six months later, when the Spanish Civil War broke out, he fled his home, along with his mother and brother, and went to live with his mother's aunt, leaving everything behind. He attended a Jesuit school there along with his brother. He became a Jesuit novitiate when he was fifteen and was sent to India in 1949 as a missionary.^[3][4][5]

Years in India

In India, Vallés attended Madras University and completed an MA in mathematics with first class honours in 1953. There, he learned English to complete his studies. He later started learning the Gujarati language, as he was asked to teach mathematics at the newly opened St. Xavier's College in Ahmedabad, which had Gujarati students. He learned Gujarati for two years, and later practised writing it during his four-year theological studies at Pune. He was ordained to the priesthood on 24 April 1958.^[3][4]

He started teaching mathematics in Ahmedabad in 1960. He translated many mathematical concepts into Gujarati for Gujarat University and coined terms for them. He helped to start and contributed regularly to the first mathematical review in an Indian language, Suganitam. He also contributed in Gujarati to the encyclopaedia Gnanganga on mathematical topics. He participated in World Mathematical Congress in Moscow, Exeter and Nice.^[3][4]

In 1960, he wrote a Gujarati book titled Sadachar, which he published with the help of his mother, since nobody agreed to publish it. It was successful and he was invited to write in the monthly Kumar by its editors. Five years later he started writing for Kumar and won its annual Kumar Prize for best writing in the monthly.^[3][4]

Later, he started writing in Sunday supplement of Gujarat Samachar in a column titled Navi Pedhine ("To the new generation"). It was successful and his articles were later published as a book. Later, he left his staff quarters in the college and started living with people to understand their life. He would live with one family for a few days and then move to the next one. He lived this way for ten years.^[3][4]
