70 years ago at Hoża 69

Exactly 70 years ago, in the autumn of 1952, two little-known employees of the University of Warsaw physics center at Hoża 69: an electrical engineer Marian Danysz, and a freshly promoted Ph.D. Jerzy Pniewski announced a surprising discovery that atomic nuclei may contain not only protons and neutrons but also quite mysterious entities called V-particles. It was the beginning of hypernuclear physics which became a flourishing branch of nuclear physics. As the last living witness of those events, I shall present some original documents and an account of what appeared to be the most important experimental discovery in the history of Warsaw university physics.
