Pravec at Ondřejov. Karel Raušal (1906-1983), Czech jurist and an honorary member of the Czechoslovak Astronomical Society, was an enthusiastic amateur astronomer known for his skill in astronomical photography and as excellent teacher. He was instrumental in building the university and public observatories in Brno in the 1950s.
