Jean-Paul Pier  Jean-Paul Pier (July 5, 1933–December 14, 2016) was a Luxembourgian mathematician, specializing in harmonic analysis and the history of mathematics, particularly mathematical analysis in the 20th century. Jean-Paul Pier was a graduate student in Luxembourg and at the universities of Paris and Nancy. He earned a University of Luxembourg doctorate in mathematical sciences and a French doctorate in pure mathematics. He also spent six months at the Grenoble Nuclear Research Center (1961) and a year at the University of Oregon (1966-1967). He taught mathematics at the Lycée de Garçons in Esch-sur-Alzette from 1956 to 1980. In 1971 he created the "Séminaire de mathématiques" at the Centre universitaire de Luxembourg (now the University of Luxembourg). He was a professor at the Centre from its creation in 1974 until 1998, when he retired as professor emeritus. Pier was primarily responsible for the creation in January 1989 of the Luxembourg Mathematical Society, of which he was president from 1989 to 1993 and again from 1995 to 1998. He was during the academic year 1994–1995 a visiting professor at the Université catholique de Louvain. Pier was the editor of two scholarly anthologies, which are standard works on the history of 20th-century mathematics. He organized several colloquia and conferences in Luxembourg. He was active internationally in various scientific bodies, including NATO Science for Peace and Security and UNESCO.
