In 1981, my wife Greetje and I went to Israel for the first time. I was to attend the Toeplitz Memorial Conference in Tel-Aviv organized by Israel Gohberg. But before going there we went to Haifa. There, at the Technion, I gave my very first lecture in Israel. The topic was ‘New methods for solving integral equations’. Leonia Lerer was our host. We had already met him before during one of his visits to Amsterdam.
