Marian Danysz
Marian Danysz was a Polish physicist, Professor of Physics at Warsaw University.
Son of Jan Kazimierz Danysz. In 1952, he co-discovered with Jerzy Pniewski a new kind of matter, an atomic nucleus, which alongside a proton and neutron contains a third particle: the lambda hyperon.
Ten years later, they obtained a hypernucleus in excited state, and the following year a hypernucleus with two lambda hyperons.
