As an outstanding developmental biologist of the third decade of the 20th century, the Russian scientist Alexander Gurwitsch [1, 2] tried to solve one of the most crucial problems of the life sciences, i.e. the “Gestaltbildungs” — problem, which is the question of how living tissues transform and transfer information about the size and shape of different organs. Since chemical reactions do not contain spatial or temporal patterns a priori, Gurwitsch claimed that a “morphogenetic field” is responsible for the regulation of cell growth. In particular, in his so-called “Grundversuch” (“basic experiment”), he found ample indication for the involvement of photons in the stimulation of cell division. Fig. 1 displays this famous “Grundversuch” of A. Gurwitsch.
