ABSTRACT
I met Zeldovich for the first time in 1975 in Poland during one of the biennial conferences on fluid mechanics. That year, it took place in Bielovezha, very close to the border with the USSR. At that time, such conferences provided an important opportunity for the meeting of scientists from East and West. This conference was no exception. In the West the name of Zeldovich was already legendary. It was well known that he had an unusually broad field of scientific interests. In particular, I knew that he had worked on dynamo theory and had proved a famous antidynamo theorem in 1956. I had also studied his more recent review paper written together with Samuel Vainstein (Soviet Physics Uspekhi 1972).
