Heinrich Christian Schumacher

Prof Heinrich Christian Schumacher FRS(For) FRSE (3 September 1780 – 28 December 1850) was a German-Danish astronomer and mathematician.

[2] From 1817 he directed the triangulation of Holstein, to which a few years later was added a complete geodetic survey of Denmark (finished after his death).

[3] Schumacher was chiefly occupied with the publication of Ephemerides (11 parts, 1822–1832) and of the journal Astronomische Nachrichten (founded by himself in 1821 and still being published), of which he edited thirty-one volumes.

He was buried in the Heilig Geist Kirchhof (Holy Ghost Church) in Altona.

Having become assistant to Carlos Guillermo Moesta (1825–1884), director of the observatory at Santiago de Chile, in 1859, he was associated with the Chilean geodesic survey in 1864.
