Kasimir Romuald Graff (7 February 1878 – 15 February 1950) was a Polish-German[1]astronomer.
He began studies in astronomy andphysics at theUniversity of Berlin in 1897 and graduated in 1901.[2] He began working at theBergedorf Observatory in 1909. He then worked as an assistant at theHamburg Observatory and became a professor at theUniversity of Hamburg in 1917. In 1928 he became director of theVienna Observatory,Austria. Along with astronomerMax Beyer, he worked to create the Beyer-Graff Star Atlas.
Using a 60 cm telescope, he was very adept in creating planetary maps from visual observations. He also worked on measuring radiation emitted from stars, and invented and built new instrumentation for this purpose. This included new types ofcalorimeter andphotometer detectors.
When theNazi government took over in Austria in 1938, he was forced to retire. It is likely that his family background and his rejection of the Nazi-supported philosophy of "Welteislehre" was the reason, although he officially was removed because of unproven charges ofembezzlement. He was reinstated in 1945, and he retired in 1949.
