He was born in 1921 in a Jewish family in the city of Timi\u0219oara, his father, Arthur, an inspector at the Romanian Railways, his mother, Melita, born Stillmann. Rad\u00f3 attended the Israeli elementary school in the Josephine neighborhood, then he was a brilliant student at the Israelite High School in Timi\u0219oara. <\/span><\/p>\n

In 1939 he was admitted to the Polytechnic Institute in Bucharest. Studies at the Polytechnic were overshadowed from the outset by the oppressive anti-Semitic atmosphere that had persisted there since the 1920s, with Jewish students often victims of acts of aggression by members of right-wing extremist organizations, popular with many students. In Timi\u0219oara, no Jewish student was able to study at the local Polytechnic in 1925-1944, due to the opposition of the student association. Following the \u201eracial\u201d laws of 1940, Rad\u00f3 was expelled from college and sent to labor camps. Despite the harsh conditions, he continued at any free time to secretly study mathematics problems. After the coup d'etat of August 23, 1944 and the abolition of anti-Jewish laws, Rad\u00f3 resumed his studies and graduated from the \"Victor Babe\u0219\" University of Cluj. Back in Timi\u0219oara, he taught mathematics at the Israelite High School, where he had been a student. In 1948, after the newly installed communist regime closed all private and religious schools, including the Jewish high school, Rad\u00f3 taught at a state high school and then, for a year, at the Pedagogical Institute in his hometown.<\/p>\n

In 1950 Rad\u00f3 became a teacher at Bolyai University in Cluj-Napoca, which in 1959 merged with Babe\u0219 University, under the name Babe\u0219-Bolyai University, with teaching in Romanian and Hungarian. In 1969 Rad\u00f3 was appointed university professor in this institution, a position he held until his retirement in 1985. In parallel, Rad\u00f3 worked as a principal researcher at the Computer Institute of the Romanian Academy branch in Cluj-Napoca. His doctoral dissertation in 1958 was in the field of functional equations and nomographic relations.<\/p>\n

During the period of limited liberalization of the communist regime in 1960-1970, he was a member of the editorial board of the Scientific Journal of Geometry in Basel and of the publication Aequationes Mathematicae at the University of Waterloo in Canada, where he was guest professor in 1969-1970.<\/p>\n

Ferenc Rad\u00f3 became known especially through his research in the field of geometry, functional equations, isometries in metric spaces, convex ensembles, supraannular geometries, numerical and graphical analysis, as well as in mathematical programming and its economic applications. Later, Rad\u00f3 became interested in the algebraic basis of geometry. In 1963 he used the \"branch and bound\" process to solve the problem of disjunctive programming.<\/p>\n

Rado published, among others, in the magazines \"Gazeta matematic\u0103\" and Matematikai lapok, also in the Hungarian cultural magazine from Transylvania, \"Utunk\", and in 1954 he participated in writing the memorial book dedicated to J\u00e1nos Bolyai and the annual almanac of the Hungarian cultural magazine \u201cKorunk\u201d.<\/p>\n<\/blockquote>[\/et_pb_text][et_pb_text _builder_version=”4.9.2″ _module_preset=”default” text_font_size=”16px” width=”80%” max_width=”80%” module_alignment=”center” hover_enabled=”0″ sticky_enabled=”0″]
