Hans Osten (astronomer)

from Wikipedia, the free encyclopedia

Hans Wintzer Osten (born March 31, 1875 in Bremen , Germany ; † March 29, 1936 in Montevideo , Uruguay ) was a German businessman and amateur astronomer .

Live and act

Hans Osten was the sixth child of the Bremen merchant and senator Friedrich Carl Philipp Osten and his wife Emma Johanne Lisette born. Wintzer. He attended pre-school and the humanistic grammar school in Bremen. He then completed a commercial apprenticeship and then entered a commercial business. He completed his year in the military in Schwerin .

During his school days he began to occupy himself with astronomical observations and later also with mathematical calculations. He received guidance and support from, among others, Carl Schilling , who later headed the Bremen Navigation School . He could use a telescope with a neighbor . He later had his own 2.5-inch telescope from Reinfelder & Hertel in Munich and a ring micrometer .

From 1895 to 1897 he worked on determining the position of sunspots . In 1897 he discovered the textbook on the orbit determination of comets and planets by Theodor Oppolzer in a library and began to deal with the orbit determination especially of comets and asteroids . In 1897 he submitted a work to the Astronomische Nachrichten to calculate the orbit of the comet 1896 VII (Perrine) discovered by Charles Dillon Perrine on December 8, 1896, which was later officially named 18D / Perrine-Mrkos . In 1899, the Astronomical News published an article by Hans Osten on the orbit of the asteroid Eros , which was particularly recognized in a footnote by the publisher Heinrich Kreutz as the work of a “young Bremen businessman”.

In 1907 he moved to Leipzig and worked in the sleeping wool trade. In 1909 he married Elsa M. Schlief, the niece of the business owner. During the First World War he was an adjutant on the Eastern Front . In 1916 he published a calculation of the orbit of the asteroid (481) Emita .

After the war, Hans Osten took over the representation of a wool export company for Europe, which his brother Cornelius Osten (1863-1936) , who was twelve years older than him, had founded in Montevideo. During this time he also worked on gravitation theory , relativity theory and natural philosophy . In 1925 he published the book On a New Law of Attraction and the Relative Definition of Inertia. In 1928 he went to Montevideo to support his brother in running the business and in his botanical studies. He traveled with him on research expeditions to Argentina by Mendoza and after Córdoba .

After eight years in Uruguay, he died there in 1936 shortly before his planned return to Germany. He was buried in a family vault at the Cementerio Británico in Montevideo.

Remarks

  1. ↑ According to this source , the asteroid (481) Emita is said to be named after Hans Osten's niece Emma Johanna Jacoba Kranenburg ( Emmie ). According to scientific sources such as Lutz D. Schmadel: Dictionary of Minor Planet Names. 3rd edition. Springer, Berlin 1997, ISBN 978-3-662-06615-7 , p. 81 ( limited preview in the Google book search) the origin of the name is unknown.
  2. ↑ In some sources the award year 1910 is mentioned
  3. ↑ In 1924, the “Friends of the University” protested to the Rector and Senate that the Philosophical Faculty had awarded the “wholesale merchant Hans Osten” an honorary doctorate in return for a “not particularly high” donation, see Jens Blecher: Vom Doctorateprivileg zum Doctoraterecht.
