Leopoldo Nachbin

Leopoldo Nachbin (7 January 1922 – 3 April 1993) was a Brazilian mathematician of Jewish origins[1] who dealt with topology and harmonic analysis.

He is featured in one of her short stories, called “As Grandes Punições” (The Great Punishments) in her book “Aprendendo a Viver,” by the Rocco publishing house.

[3] His monographs Topology and Order and The Haar Integral, both published by Van Nostrand-Reinhold in 1965, are regarded as exceptional expositions of the subjects.

Overall he authored ten books, most of which were published internationally, and edited a dozen tomes of the prestigious North-Holland Mathematical Studies series between 1970 and the early 1980s.

He was an invited speaker at the International Congress of Mathematicians (ICM) of 1962 in Stockholm ("Résultats récents et problèmes de nature algébrique en théorie de l'approximation"), being the first Brazilian speaker at the ICM.
