His first period, until May 1931, was spent at the University of Berlin where he worked with von Neumann . From Berlin, Herbrand went to Hamburg where he spent the month of June working with Artin Emmy Noether It is incredible how much Herbrand achieved in the short time he had to undertake mathematical research. He made contributions to mathematical logic where Herbrand's theorem on the theory of quantifiers appears in his doctoral thesis. See [5] for discussion of a gap which was found in Herbrand's proof in 1963. Herbrand's theorem establishes a link between quantification theory and sentential logic which is important in that it gives a method to test a formula in quantification theory by successively testing formulas for sentential validity. Since testing for sentential validity is a mechanical process, Herbrand's theorem is today of major importance in software developed for theorem proving by computer. Herbrand also worked on field theory considering abelian extensions of algebraic number fields . In the few months on which he worked on this topic, Herbrand published ten papers.

JACQUES HERBRAND Jacques Herbrand (19081931) In July, 1931, Jacques Herbrand worked with Emmy Noether in Göttingen. Near the end of the month, he went mountain-climbing in the French alps with two friends. http://www2.evansville.edu/ck6/bstud/herbrand.html
Extractions: mathematician In July, 1931, Jacques Herbrand worked with Emmy Noether in Göttingen. Near the end of the month, he went mountain-climbing in the French alps with two friends. There, in the granite of La Bérarde, near Isére, he fell to his death. It is written in Auguste Dick, Emmy Noether 1882-1935, Birkhäuser Verlag, Basel, 1970 (in German); translated to English, Birkhäuser, Boston,1981 that "Emmy Noether was profoundly shaken by the fate of this extraordinarily promising young mathematician." Months after the event, she wrote, "Mir geht der Tod von Herbrand nicht aus dem Sinn. - I can't get Herbrand's death out of my mind." Herbrand had finished his doctorate at École Normale Supérieure in Paris under Ernest Vessiot in 1929, having matriculated there at the exceptional age of 17 and having ranked first in the entering class. In October, 1929, Herbrand joined the army. In 1931, he was awarded a Rockefeller fellowship that enabled him to study in Germany, first with John von Neumann in Berlin, then during June with Emil Artin in Hamburg, and finally, in July, with Emmy Noether. Although Herbrand his best remembered for work in logic and metamathematics, his interests included algebra in general and ring theory in particular, and it was in this connection that he was collaborating with Noether.

Extractions: Spécification des formules de Horn en termes de polarités Harrop Ronald (1926) [ Harrop 56 Harrop 60 ]. Après avoir montré que des énoncés de la forme (ou ) ne sont démontrables que si soit soit l'est (ou l'est pour un terme ), Harrop a recherché des résultats similaires pour des énoncés de la forme (ou ). La question est donc de savoir si on peut se contenter de preuves constructives pour démontrer ces énoncés. Harrop a montré que pour que la démontrabilité de ces formules puisse se réduire à la démontrabilité constructive, il fallait que les occurrences de et dans la formule soient contraintes. Cette contrainte aboutit à la notion de formule de Harrop, et à celle de formule héréditaire de Harrop si on veut que toutes les étapes de la démonstration de ou (ou ) soit constructives.

Brewer and Martha K. Smith, editors, Emmy Noether: A Tribute to Her Life and Work, Marcel Dekker, New York, 1981: Jacques Herbrand, born on the 12th of February, 1908, in Paris, was killed on the 27th of July, 1931, while mountain-climbing in the French Alps. One of the strongest mathematical talents has passed on with him, just during a time of the most intensive work, while he was full of ideas for the future. The last year of his life, which he spent with a Rockefeller scholarship in Germany, brought him into close contact, both scienfically and personally, with a number of German mathematicians . . .
