[Christmas article: Christmas article: The professors take up the master's program at Rigshospitalet]

Caricatures highlight personal characteristics. The caricature drawing of the four prominent professors from the transition from the Royal Frederik's Hospital to Rigshospitalet, Copenhagen in 1910, shows the dominant surgeon Niels Thorkild Rovsing (1862-1927), who takes up half of the drawing; the reserved organizationally interested physician Knud Helge Faber (1862-1956) in the middle; the thoughtful surgeon Oscar Thorvald Bloch (1847-1926), and the somewhat isolated physician Hans Christian Joachim Gram (1853-1938), who became known for his staining method to separate Gram-positive from Gram-negative bacteria.
