from Wikipedia, the free encyclopedia

Bernhard Friedrich Freiherr von Krosigk (born December 8, 1656 in Magdeburg , †  September 11, 1714 in Herxen , Netherlands ), Lord of Poplitz , Laublingen , Gröna , Plötzkau and Beesen , was a secret councilor and operator of astronomical studies.

Life

origin

Bernhard Friedrich came from the Krosigk family . He was the second son of Vollrad Ludolf von Krosigk (1620–1671) and his wife Dorothea, born von der Asseburg (born December 1, 1624 in Neindorf; † November 23, 1674 in Beesen); next to his older brother Vollrat Busse and the younger Levin August.

Act

After the death of his father, the Poplitz estate, among other things, fell to him when the estate was divided. He then built Poplitz Castle and became the progenitor of the Poplitz line.

Since he was mainly concerned with astronomical studies, he had the roof of the new Poplitz manor house equipped with a gallery for observing the stars. He also had an observatory built in Arkhangelsk at his own expense .

Bernhard Friedrich von Krosigk first worked in Wolfenbüttel as a Brunswick court marshal , secret councilor and colonel. In 1690 he was authorized by Anton Ulrich , Prince of Braunschweig-Wolfenbüttel , to go to Haag. Later the Prussian King Friedrich I appointed him to Berlin as a privy councilor.

In Berlin, too, he set up an observatory on his house in the Neu-Cölln district on Wallstrasse. While the Berlin observatory was still under construction for the founded Prussian Academy of Sciences , its first astronomer Gottfried Kirch was able to use the private observatory in Krosigk. In 1704 he financed an expedition to South Africa to the Cape of Good Hope, Peter Kolb , whom he had hired as secretary on his Poplitz estate in 1702 . There Kolb set up the first observatory in South Africa and undertook astronomical and meteorological research. From 1705 Krosigk had his Berlin private observatory run by the astronomer Johann Heinrich Hoffmann and from 1706 to 1709 the astronomer Johann Wilhelm Wagner was employed at it; He was supposed to measure the parallax of the moon parallel to Kolb in South Africa in order to determine the distance of the moon from the earth more precisely with the simultaneous observations of two points on the earth as far apart as possible .

In old age, Bernhard Friedrich von Krosigk took over the property in Ober-Yssel in Holland and retired there to his Herxen estate a year before his death.

family

Krosigk married Anna Hedwig Sophie von Steinberg in 1688 (born August 6, 1665 in Bodenburg , † August 8, 1721 in Isenbüttel ). From this marriage emerged:

  • Marie Antoinette von Krosigk (born January 6, 1696 in Poplitz , † October 18, 1759 in Köthen ) ∞ Johann Adolf von Krosigk (1666–1728), lord of Hohenerxleben and Rathmannsdorf
  • Dorothea Luise († 1749) ∞ Heinrich Vollrath von Campe († June 16, 1743)
  • Rudolf August von Krosigk (1700–1739)
  • Heinrich von Krosigk (1700–1746) ∞ Charlotte Elisabeth von Miltitz (1704–1788)

Honors

In honor of the committed amateur astronomer , the asteroid (6842) Krosigk, discovered in 1960, was named after him on October 6, 1997 at the suggestion of A. von Alvensleben and Joachim Schubart .
