Ribenboim was born into a Jewish family in Recife, Brazil. He received his BSc in mathematics from the University of São Paulo in 1948, and won a fellowship to study with Jean Dieudonné in France at the University of Nancy in the early 1950s, where he became a close friend of Alexander Grothendieck.^{[1]}
He has contributed to the theory of ideals and of valuations.^{[2]}

Ribenboim has authored 246 publications including 13 books. He has been at Queen's University in Kingston, Ontario, since the 1960s, where he remains a professor emeritus.

Jean Dieudonné was one of his doctoral advisors. Andrew Granville has been a doctoral student of Ribenboim.

The Ribenboim Prize of the Canadian Number Theory Association is named in his honor.

In 1951, Ribenboim married Huguette Demangelle, a French Catholic woman whom he met in France. The couple have two children and five grandchildren, and have lived in Canada since 1962.^{[3]}
