I had the chance to meet Federico in a series of conferences organized by Rodolfo Bonifacio of University of Milan at Gargnano on Garda Lake. The last time I met him was on September 2003 at this conference.
Federico was an associate professor at University of Milan, an expert in quantum optics, and it was a real pleasure to have the chance to share some time with him. Federico was a nice and competent person and we have had several discussions with a good beer there in Gargnano. When conference gave a break, with Federico and a colleague of INFN we took his car and went to the highest point around the lake to see a breathtaking landscape. That day we had a lot of interesting discussions that signed the start of a friendship that lasted until he let me know he was ill and was retiring.
Federico was instrumental in my work helping me to recover material otherwise unreachable. We have had a constant exchange of emails in these years and was my pleasure to make him compliments for his preferred team, Internazionale (Inter), that was winning all. Now I am getting emotional for this bad news. He left us on May for a very bad illness and I should say that I feel that someone important in my life is missing.
He will be remembered for his work, the kindness and the competence. He is survived by his wife.
