About the author
Born in Stockholm on October 30, 1860, Karl Petrus Theodor Bohlin was a Swedish astronomer, mathematician, and author. He studied at Uppsala University, earned his doctorate in 1886, and later became a professor connected with the Royal Swedish Academy of Sciences and director of Stockholm Observatory.
Alongside his scientific research, Bohlin wrote books that introduced astronomy and the history of science to a broader public. One of the works associated with him in modern library catalogs is Jorden och solsystemet, a historical account of changing ideas about the Earth and the solar system.
He died in Stockholm on May 25, 1939. Today he is remembered both for his contributions to celestial mechanics and for writing that helped make astronomy more accessible.
