Rudolf König (18 August 1865 – 30 January 1927) was an Austrian merchant, amateur astronomer and selenographer.

Biography
König went to hight school in Vienna and later the business school in Leipzig. He was the son of Georg König, a fur businessman. While he worked for his father’s fur business, he attended lectures at the University of Vienna and acquired astronomical knowledge. König and his wife Josefine Antonie König had two children.

Private Observatory
In 1906, König built a private observatory on top of his house in Vienna. The instrument was designed for astrophotography and consisted of Carl Zeiss’ 18 and 21cm calibre birefringence telescopes on a huge equatorial shelf. It was on his observatory he observed the carter König named after him and completed his study for his deceased friend the draftsman and selenographer Johann Kreiger. In 1929, after König’s death, his widow sold the telescope to the “Bohemian Astronomical Society” to build a public observatory in Prague. König’s observatory is now operated by the Stefanik Observatory in Prague, and his specialist library as well as other astronomical devices were collected by Vienna University Observatory.

Study for Kreiger’s publish
König was a friend of Krieger as well as the co editor of Kreiger’s "Mond Atlas". After Krieger’s death, he left mass unorganized descriptions and sketches of the moon observation. König then spent two years’ observation on his observatory, and within five years arranged two Krieger’s volumes including his reproduction drawing and sketches, and requisite letterpress.
