Dario Graffi (10 January 1905 – 28 December 1990) was an influential Italian mathematical physicist, known for his researches on the electromagnetic field, particularly for a mathematical explanation of the Luxemburg effect,[3] for proving an important uniqueness theorem for the solutions of a class of fluid dynamics equations including the Navier-Stokes equation,[4] for his researches in continuum mechanics and for his contribution to oscillation theory.[5]
Life and academic career
Dario Graffi was born in Rovigo, the son of Michele, a yarn wholesale trader and of Amalia Tedeschi.[6] He attended the Istituto tecnico in his home town, specializing in physics and mathematics, but got his diploma in Bologna in 1921, where his family had moved a year before.[6]
He graduated from the University of Bologna in Physics in 1925,[7] when he was 20,[8] and in mathematics in 1927,[7] when he was 22:[8] both the degrees were awarded cum laude,[9]
Honors
He was awarded the Golden medal "Benemeriti della Scuola, della Cultura, dell'Arte" in 1964, and a year later, the Accademia Nazionale dei Lincei awarded him the Prize of the President of the Italian Republic.[2]
Work
Research activity
Graffi is known for his researches on the electromagnetic field, particularly for a mathematical explanation of the Luxemburg effect, for proving an important uniqueness theorem for the solutions of a class of fluid dynamics equations including the Navier-Stokes equation,[10] for his researches in continuum mechanics and for his contribution to oscillation theory.
Selected publications
Graffi published 181 works.[11] lists of his publications are included in references (Cercignani 1992) and in the Consiglio Scientifico del G.N.F.M.|1999}}|biographical section of his "Selected works" (1999, pp. XX–XXVI): however, the set of lecture notes (Graffi 1981) is not listed in any of his publication lists.

In this paper, written only few years after the discovery of the effect itself, Dario Graffi proposes a theory of the Luxemburg effect based on Volterra's theory of hereditary phenomena.
