The objective of this paper consists in presenting the reaction of the physicist Guido Beck (1903-1988) towards the political events that occurred in the University of Buenos Aires (UBA), during the second term of 1966. It is not our intention to write a deep treatise on the problem, but to outline some of the ideas that Guido Beck had on the relation between science, State and society in South-American context. That will be done by describing his reaction to the well-known 'night of the long police batons'. Beck had always been sensitive to the political instability in Argentinean academic system, once that political and ideological disputes could jeopardize the work towards the establishment of a scientific community in that country. As a conclusion, 1 defend the thesis that in Beck's point of view the physicists at UBA had misunderstood the importance they had to Argentinean government and to part of the population in that same country.
