On the occasion of his retirement, yesterday afternoon Prof. Guido Pampaloni greeted all the students and staff of the Department of Chemistry and Industrial Chemistry with an outstanding seminar on the history of chemistry dedicated to Geoffrey Wilkinson & Ernst Otto Fischer, the two pioneers of Organometallic Chemistry. The seminar was preceded by an introduction of PhD students of our Doctoral School in Chemical and Materials Sciences. The large audience in the room demonstrated the esteem and affection of our Department for Prof. Pampaloni, to whom we wish a happy retirement!
