According to
Personality traits
He is unanimously remembered as a real
An excellent teacher himself, capable to arose curiosity and enthusiasm by his lessons,[21][26] he admired and respected much his own:[27] however, this was quite common for the Italian scientists of the same and the preceding generations, who were advised in the early days of their scientific career by some of the best Italian scientists ever.[28] His doctoral advisor was Francesco Severi: other great Italian mathematicians where among his teachers. Guido Castelnuovo, Federigo Enriques, Enrico Bompiani, Tullio Levi-Civita Mauro Picone and Antonio Signorini were all working at the Sapienza University of Rome when Enzo Martinelli was a student there, following their lessons: Zappa (1984) describes the activity of the institute of mathematics during that period as extremely stimulating.[29]
Another central aspect of his personality was a deep sense of
Work
Research activity
Fin troppo meticoloso, scriveva più volte ogni suo lavoro, curandone fin nei minimi particolari sostanza e forma, fino a renderli di piacevole lettura. È difficile trovare nei suoi scritti un concetto che possa essere espresso in modo migliore.[34]
— Dionisio Gallarati, (Gallarati 2000, p. 45).
He is the author of more than 50 research works, the first of which was published when Martinelli still was an undergraduate student:
Teaching activity
The aspects of his personality described before and his deep professional commitment also made him a great teacher:
