摘要：I met Héctor for the first time in the summer of 1968. I was a beginning graduate student and Héctor with a Swedish family wanted to have Sweden as a base for his summer activities. He had written to Gunnar Källén to ask if he could stay in Lund for the summer, but Källén had replied that Lund only had funding for important people, so Héctor had then asked Jan Nilsson who gladly had invited him. He reminded me immediately of a poem of Hjalmar Gullberg, one of the leading Swedish poets of last century who in a poem describes a person with the words in my translation. "He came as a wind. What does the wind bother about prohibitions." (It sounds better in Swedish.) Héctor came as a rising star in physics after a very successful year having essentially started what was to become Dual Models and eventually String Theory. I was the youngest graduate student but he somehow picked me out and told me about the new fantastic things that were happening. I had on my own studied Finite-Energy Sum Rules even though my advisor Jan Nilsson had asked me to other things, and my early contacts with Héctor convinced me to go on and follow his subject. I am very grateful for that. Somehow when you look back at your career you find that certain accidental encounters have formed your scientific life.
