History

The company was founded in 1922 by locksmith Anton Paar. He trained his daughter, Margareta Platzer, in the 1920s to become a locksmith. She and Otto Kratky developed the Kratky X-ray small-angle camera. In 1963, Platzer's son-in-law Ulrich Santner took over the management of the company. In 1997, his son-in-law Friedrich Santner joined the management. Since 2002 he is the sole managing director. In 2003, the family business was incorporated into a charitable organization, the Santner Foundation. On February 12, 2018, Anton Paar acquired Quantachrome Instruments, a manufacturer of scientific instruments. In August 2023, the German company Brabender was bought by Anton Paar and has since continued as Anton Paar TorqueTec. In 2020, Friedrich Santner's sons became part of the management. Jakob Santner took over the position as CTO and Dominik Santner as COO; Friedrich Santner remains CEO.
