Karl Müller (astronomer) Wikipedia
Karl Müller (1866–1942) was a Czech government official and amateur astronomer.
He collaborated with Mary Adela Blagg on standardizing the nomenclature of formations on the Moon for the Lunar Commission of the newly formed International Astronomical Union. Together with Blagg he produced a two volume set in 1935, entitled Named Lunar Formations, that became the standard reference on the subject.
The crater Müller on the Moon is named after him.
