The portfolio entitled ‘The Doctor and the Pharmacist’ is included in the group ‘Classes and Professions’ within August Sander’s photographic project ‘People of the 20th Century’. In this portfolio, Sander introduces both representatives of alternative healing methods, such as ‘Herbalist’ (1929), and practitioners of orthodox medicine as represented here by the doctor. Such juxtapositions were crucial to his vision of the project as a whole, in which individual images depend on and inform each other. Dr Carl Robert Schlayer was photographed in his white-tiled Berlin laboratory, two large glass cylinders in a metal frame to his left behind him emphasising his medical authority. The doctor stands in a contrapposto pose, one knee slightly bent, his left hand in his trouser pocket, his right holding his watch chain at chest height. His eyebrows are drawn together behind his glasses in an expression of stern concentration.
