This chapter indicates that despite the terrible situation in Germany, the study of bee behaviour persisted until 1940, and recovered in Frankfurt, Freiburg and Münich after the war. However, the orthodox view did not change because the very doggone persistence of those in charge did not change. Spectral sensitivities of the receptors were unknown until 1964, and there was no alternative theory. Moreover, the culture that protected status and reputations has not changed to this day, and even grows, with signs that the huge research effort of all prosperous nations is slowed down by ever more conservative bureaucratic power dedicated to control of the funds and objectives.
