In December 1938, the German chemists Otto Hahn and Fritz Strassmann sent a manuscript to Naturwissenschaften reporting they had detected the element barium after bombarding uranium with neutrons ; simultaneously, they communicated these results to Lise Meitner.

* October 6 – Otto Fritz Meyerhof, German-born physician and biochemist, recipient of the Nobel Prize in Physiology or Medicine ( b. 1884 )

** Otto Fritz Meyerhof, German-born physician and biochemist, recipient of the Nobel Prize in Physiology or Medicine ( d. 1951 )

* Physiology or Medicine – Archibald Vivian Hill, Otto Fritz Meyerhof

Development of this process was aided by German chemist Fritz Strassmann, who later went on to discover nuclear fission with German chemist Otto Hahn and Swedish physicist Lise Meitner.

* 1939 Otto Hahn and Fritz Strassmann bombard uranium salts with thermal neutrons and discover barium among the reaction products

Irène ’ s group pioneered research into radium nuclei that led a separate group of German physicists, led by Otto Hahn, Lise Meitner, and Fritz Strassman, to discover nuclear fission ; the splitting of the nucleus itself and the vast amounts of energy emitted as a result.

The New York writer Paul Goodman, who was co-founder with Fritz Perls of the Gestalt method of psychotherapy, one of the most popular in the world today, and one that makes Otto Rank's " here-and-now " central to its approach, described Rank ’ s post-Freudian ideas on art and creativity as “ beyond praise ” in Gestalt Therapy ( Perls, Goodman and Hefferline, 1951, p. 395 ).

Parallelling the work of German Otto Fritz Meyerhof he elucidated the processes whereby mechanical work is produced in muscles.

Wilhelm Carl Werner Otto Fritz Franz Wien (; 13 January 1864 – 30 August 1928 ) was a German physicist who, in 1893, used theories about heat and electromagnetism to deduce Wien's displacement law, which calculates the emission of a blackbody at any temperature from the emission at any one reference temperature.

A large number of senior officers were directly or indirectly implicated, headed by Field Marshals Kluge, Rommel ( very peripherally ) and Witzleben, and Generals Falkenhausen, Erich Fellgiebel, Friedrich Fromm, Paul von Hase, Gustav Heistermann von Ziehlberg, Otto Herfurth, Erich Hoepner, Fritz Lindemann, Friedrich von Rabenau, Hans Speidel, Helmuth Stieff, Stülpnagel, Fritz Thiele, Georg Thomas and Eduard Wagner, as well as Admiral Wilhelm Canaris.

" Historian Fritz Trautz went so far to write: " The silly fairytale, which to this day moves many pens and has found much belief, was fully disproved in Otto Mittelstädt's book.

In December 1938, the German chemists Otto Hahn and Fritz Strassmann sent a manuscript to Naturwissenschaften reporting they had detected the element barium after bombarding uranium with neutrons ; Lise Meitner and her nephew Otto Robert Frisch correctly interpreted these results as being nuclear fission.
