Friedrich Wilhelm August Argelander was born on the 22nd of March in the year of 1799 in Memel in East Prussia, presently known as Klaipeda in Lithuania. Between 1852 and 1861, he mapped out the position of all the stars of the Northern Hemisphere, which were above the ninth magnitude. Between 1859 and 1862, he published them in the great star catalogue and named it the Bonner Durchmusterung. This was one of the fascinating works of Friedrich Wilhelm August Argelander and thus was reissued in 1950.
Friedrich Wilhelm August Argelander was a Prussian astronomer who became famous as one of the celestial map makers of modern era, In 1822 he completed his Ph.D., under the supervision of Friedrich Bessel at Konigsberg. From 1823 till 1837, he served as the head of the Finnish observatory at Turku, which was in Helsinki at that point of time. Then he moved to Germany, where he became well-known because of his work in recording the positions of stars.
Together with Eduard Schonfeld and Adalbert Kruger Friedrich Wilhelm August Argelander made the star catalogue, which is known as the Bonner Durchmusterung, and was issued between the period of 1852 and 1859. This work enlightened people with the position and brightness of more than 324,000 stars, which were mostly in the northern hemisphere. Moreover this was the last map of stars, which was published without using any photography. In 1863 he founded an international organization of astronomers called the Astronomische Gesellschaft. In the same year Argelander won the Gold Medal of the Royal Astronomical Society. This great soul left the world on the 17th of February in the year of 1875.
