The charitable foundation Genesungsheim Kalksburg was founded under the patronage of the then Minister of Social Affairs Anton Proksch and at the initiative of Prof. Hans Hoff and Dr. Emil Tuchmann. A team of 19, including two doctors and four nurses cared for 65, mostly male, patients.
A 15-bed long-term treatment unit for drug addicts was opened at Breitenfurterstraße 517.
After the death of Anton Proksch the institute was renamed Anton Proksch Institute.
Dr. Rudolf Mader succeeded Prof. Cornelius Kryspin-Exner as head of the Anton Proksch Institute.
The number of beds was increased to 160, a half-way house with 10 beds was opened for alcoholics.
In the years that followed, the facility was enlarged, adapted and new buildings were constructed; the number of beds was increased to the current 276.
Prof. Michael Musalek became the head of the Anton Proksch Institute following the retirement of Prof. Rudolf Mader.
