Peter Carl Ludwig Schwarz[1] (Julian, O.S.: 23 May 1822,[1] Danzig-Gdańsk – 17 September 1894; Gregorian, N.S.: 4 June 1822 - 29 September 1894,[2] St. George's?; Buried: Tartu)[1] (referred to mostly as Ludwig Schwarz),[2] was a Baltic German astronomer[3] of Imperial Russia, explorer, and professor[1] of astronomy at the University of Dorpat[4] honored with the Konstantin Medal[note 1] of the Imperial Russian Geographical Society.[5] Schwarz also was a recipient of the Demidov Prize[5][note 2] of the Academy of Sciences of St. Petersburg in 1865 for his work in geodesy.[5]

Palaeoarctic Siberian Asia Expeditions

Following assignment by Friedrich Georg Wilhelm Struve as a field expedition astronomer (1849-1853) to study the Amur River,[5][3] astronomer Schwarz led (1854-1862) the East Siberian Expedition of 1855 which extensively explored unknown and unmapped territory in Eastern Siberia.[6][5]

The Siberian expedition went into central Asia, southeastern Asia, and northern China.[5] Some of the routes travelled were as long as 10,000 miles.[5] Utilizing his prior Amur field knowledge of astronomy he would determine geographical positions of certain points (geodesy) for preparation of geographical maps.[5] The information would later be used in planning the construction of the Trans-Siberian Railway systems and others in southeast Asia.

The volumes reporting the results of the expedition were published in 1864.[5] The separate tomes concerning the vegetation and wildlife reports were prepared by the expedition's botanist and zoologist Gustav Radde.

Dorpat Observatory

Ludwig Schwarz served as the Director of Dorpat Observatory[2] (now Tartu Observatory) from 1872[7][note 3] to 1891,[2] succeeding Thomas Clausen who held the position from 1866 to 1872.[7] Upon the retirement of Schwarz from the directorship on 1 September 1891 the position became the responsibility of Grigori Levitski who held it until 1908.[8]

During his tenure in later life he conducted studies of one third of the 10,000 celestial stars visible at Tartu.[5]

Legacy

Radde's warbler, a leaf warbler bird that breeds in Siberia and winters in southeast Asia, bears a scientific name (Phylloscopus schwarzi) that commemorates Schwarz in its latter half.[9] The bird was described in 1863 by naturalist and fellow explorer Gustav Radde who served in the East Siberian Expedition of 1855 led by Schwarz.[9] The Spanish variant common name of the bird, Mosquitero de Schwarz (English: Schwartz Flyer or Schwartz Musketeer), represents an explorer or adventurous "flyer" or musketeer (Spanish: mosquetero; French: mousquetaire).
