In memoriam: Domenico (Mimmo) Grimaldi

In Italy, everybody active in the I&M field could say that they've known Domenico (Mimmo) Grimaldi forever, even if they lived hundreds of kilometers apart, they studied at different universities and worked in different universities. We all shared the same interest and passion: I&M. In Italy, there were very few professors teaching I&M when Mimmo, and those like us, started careers, many years ago as young assistant professors. Our professors, who triggered and nurtured our passion for I&M, were so wise to understand not only the importance of this subject in a world that is more and more relying on measured quantities and data, but also that the I&M culture could be developed and disseminated by people who were deeply engaged in this field and in finding common solutions to the different I&M problems. They organized, on a regular basis, several scientific meetings where these issues could be discussed among all of us. Their wisdom was so great that they also understood that good friends could be much more "efficient" rather than only colleagues. So those meetings - let's not forget that we live in Italy! - always ended with a good dinner, with all of us sitting at the same table and sharing the same good food and good wine. No wonder that the generation to whom Mimmo belonged developed such a strong friendship, and the awareness that we had not only good colleagues, but also good friends. Mimmo was one of the quietest of us, always respectful of everybody else's ideas but also very determined in expressing his own ones. His competences in the ADC field and, more recently, in biomedical measurements represented a reference for all of us.
