Georg von Neumayer

Georg von Neumayer

Georg Balthazar von Neumayer (21 June 1826 – 24 May 1909), was a German polar explorer and scientist who was a proponent of the idea of international cooperation for meteorology and scientific observation.

Biography

Early years

Born in Kirchheimbolanden, Palatinate, Neumayer finished his education in geophysics and hydrography in Munich, Bavaria in 1849; and becoming much interested in polar exploration, continued his studies in terrestrial magnetism, oceanography, navigation, and nautical astronomy. To obtain practical experience he made a voyage to South America, and after his return gave a series of lectures at Hamburg on Maury's theories of the ocean, and recent improvements in navigation. He then decided to go to Australia, shipped as a sailor before the mast, and arrived at Sydney in 1852.

After trying his fortune on the goldfields, Neumayer gave lectures on navigation to seamen, and spent some time in Tasmania at the observatory in Hobart. He returned to Germany in 1854 convinced that Australia offered a great field for scientific exploration, obtained the support of the King of Bavaria and encouragement from leading British scientists. He sailed again for Australia and arrived in Melbourne in January 1857. He asked the government of Victoria to provide him with a site for an observatory, about £700 for a building, and about £600 a year for expenses. He had brought with him a collection of magnetical, nautical and meteorological instruments valued at £2000, which had been provided by the King of Bavaria.

Neumayer suggested as a suitable site a block of land not far from the present position of the observatory, but this was not granted. He was, however, allowed the use of the buildings of the signal station on Flagstaff Hill creating the Flagstaff Observatory for Geophysics, Magnetism and Nautical Science at what is now Flagstaff Gardens in Melbourne, Australia. From 1 March 1858 he carried on the systematic registration of meteorological and nautical data. A few weeks later he added regular observations on atmospheric electricity and changes in the magnetic elements.

Burke and Wills Expedition

William John Wills, second-in-command of the Burke and Wills expedition worked under Neumayer at the Flagstaff Observatory until the expedition departed from Melbourne on 20 August 1860. Neumayer was a member of the Exploration Committee of the Royal Society of Victoria which organised the Expedition. Neumayer joined the Expedition at Swan Hill in order to conduct his magnetic observations. He remained with Burke and Wills as far as the Darling River at Bilbarka, before returning to the settled districts of Victoria.

Legacy

He published in 1860, Results of the Magnetical, Nautical and Meteorological Observations from March 1858 to February 1859, and did a large amount of travelling in Victoria in connection with his magnetic survey of the colony. He published his Results of the Meteorological Observations 1859-1862 and Nautical Observations 1858-1862 in 1864, and in the same year returned to Germany. In 1867 he brought out his Discussion of the Meteorological and Magnetical Observations made at the Flagstaff Observatory, and in 1869 appeared his extremely valuable Results of the Magnetic Survey of the Colony of Victoria—1858-1864.

Later, he organized the "Gazelle Expedition." (1874-1876) and was director of the hydrographic organisation "Deutsche Seewarte" (1876-1903). He chaired the International Polar Commission in 1879 together with Karl Weyprecht, founding the first International Polar Year 1882/83 and the Antarctic Year 1901. In 1895, von Neumayer had established the German Commission for South Polar Exploration, which culminated in the First German Antarctica Expedition in 1901, the so-called Gauss expedition.

In 1890 he co-authored the first cloud atlas.[1]

Polar explorer Roald Amundsen came to study under von Neumayer in 1900.[2]

Neumayer died in 1909 in Neustadt an der Weinstraße. He gave his name to the German Polar Research Station in Antarctica, the now abandoned "Neumayer Station". This year-round manned station is totally covered with ice and snow (buried 10 meters under the surface) and is situated in the Weddell-Sea area (08 15W, 70 35S). The successor was the Neumayer Station II which was then abandonded itself. The only station in use now is the Neumayer Station III. Research topics are permanent observations of the Earth's magnetic field, seismological registrations, infrasonic, meteorological and air chemistry investigations.
