Nicola Badaloni at the age of 24, officially took over the management at the Municipality of Trecenta on 11.7.1878.
In the period between 1885 and 1886 he became assistant to the chair of materia medica and pharmacology at the University of Padua.
In 1899 he obtained a teaching position in special demonstrative medical pathology at the Royal University of Perugia and was subsequently appointed professor of demonstrative medical pathology at the University of Naples.
Finally, in 1907 he was appointed member of the Superior Council of Health and was rapporteur for social-health bills on the abuse of narcotic substances.
However, scientific affirmations and recognitions are not enough to dissuade him from Polesine; for him, being a doctor is not a profession, but rather a real vocation. In fact, he accepted from the “Provincial Deputation” of Rovigo to investigate the causes of pellagra and the terrible effects that this disease produced on the organism, a real plague of the Polesine in those years. It is research done with passion, in which it highlights not only the darkest aspects of the disease, but also investigates and describes the entire economic, moral and social environment. His investigation, which will last four years, will however be opposed and his results will be made to disappear, so much so that today only a bare summary of his work appears.
