Jewish scientists in the 20th century

A series of articles by Prof. Alex Gordon on the Jewish scientists who shaped science in the twentieth century

A series of articles by Prof. Alex Gordon presenting the stories of Jewish scientists, mathematicians, physicists, chemists, biologists, doctors, inventors, and thinkers who worked in the twentieth century.

The articles deal with their discoveries and their impact on science and culture, but also with their personal lives, their Jewish identity, and their relationships with the societies and regimes within which they operated. Among the protagonists of the series are Nobel Prize winners alongside researchers whose important contributions have not always received the recognition they deserve.

The episodes are presented in series order, and each article includes links to the previous episode, the next episode, and the full episode list.
