ABSTRACT
Memoirs are usually preceded by a standard apology to the effect that the authors cannot avoid telling at least a little bit about themselves and their relationship with the person about whom they are writing. In my case, the appropriate apologies should probably be presented a bit differently. Since my acquaintance with physicists about whom I’ve been called upon to write was always connected in one way or another with my father, Yakov Il’ich Frenkel, who was their friend, colleague, or teacher; I must also say a few words about him. This will be the case here, as I write about Yakov Borisovich Zeldovich.
