[1] Cougnet made important contributions to Argentine science and is considered a pioneer in her field of research, together with Estrella Mazzoli de Mathov,[2] Juana M. Cardoso, Adulio Cichini, Horacio Ghielmetti, Emma V. Pérez Ferreira, Juan G. Roederer and Pedro Waloschek.
[3] She also served as thesis director for a local doctoral student researching nuclear reactions recorded at the Bevatron particle accelerator in Berkeley, California.
At the end of 1949, Cougnet went to Germany and visited the laboratory of Werner Heisenberg at the Max Planck Institute in Göttingen where she learned about the work with nuclear emulsions directed by Martin Teucher.
[4] In June 1966, the political landscape in Argentina turned dangerous because of the coup d'état, so she and Roederer emigrated to Colorado in the United States with their four children and three surviving parents.
[1] Beatriz was the wife of Juan G. Roederer,[5] an Italian-born Argentine physicist, whom she met during her high school studies, and with whom she had four children: Ernesto, Irene, Silvia and Mario.
