Up to thirty years after the discovery of X-rays the results in veteri
nary radiology were rare and hardly systematic. This fact can be reaso
ned by the low power of the existing X-ray units, the incooperativity
of animals and their unfavourable anatomy in contrast to human beings.
In 1927 the first independent department of radiology within the Univ
ersity of Veterinary Medicine Vienna, was founded and well equipped. T
he head of the department, Alois Pommer, worked for a thorough basic k
nowledge, therapeutic and diagnostic advances in veterinary radiology
in analogy to human medicine. He influenced significantly the future d
evelopment of veterinary radiology. This paper gives a summary of the
achievements in veterinary radiology in Vienna until World War II.
