"Today marks the thirtieth anniversary of Pietro Valdoni's death, and we would like to recall an episode involving the great surgeon. As everyone will remember, it was he who operated on Palmiro Togliatti, saving his life after he was wounded in the head by Pallante's revolver. When he received the bill, Togliatti found it steep and accompanied the payment with these words: “Here is the balance, but it is stolen money”. Valdoni replied: “Thank you for the cheque. I am not interested in where it came from”."
