Johann von Lamont

 
Scientist: Johann von Lamont

Scottish–German astronomer (1805–1879)

Lamont, whose father worked in the customs service, came from an old but impoverished family in Braemar, Scotland. After his father's death in 1816 the young Lamont was sent to the Scottish Benedictine monastery at Ratisbon and given a rigorous mathematical training from the abbot. He was admitted to the Munich Academy of Science in 1827 and became assistant astronomer at the Bogenhausen Observatory in 1828 and director in 1835. In 1852 he became professor of astronomy at Munich University.

Lamont published a major catalog in six volumes (1866–74) of 34,674 small stars but his most important work was on terrestrial magnetism. He began keeping local records in 1836 and performed magnetic surveys of Bavaria, France, Spain, Denmark, and North Germany. He announced the important discovery of the Earth's (approximately) ten-year magnetic cycle in 1850, only a few years after Heinrich Schwabe had announced a similar cycle for sunspots. It was not long before scientists began to speculate on a possible connection.

Lamont, Johann von ('hän fən lä'mônt), 1805-79, Scottish-German astronomer and magnetician, b. Scotland. In 1817 he went to Ratisbon to study at the seminary. He remained in Germany to work in the new observatory at Bogenhausen. Lamont became its director in 1835 and professor of astronomy at the Univ. of Munich in 1852. His most important work was in the field of terrestrial magnetism; he made (1849-58) magnetic surveys in Bavaria, France, Spain, N Germany, and Denmark. In 1850 he announced the theory of the magnetic decennial period and in 1862 the discovery of earth currents. In astronomy he cataloged 34,674 stars, measured nebulae and clusters, and made studies of Uranus. Lamont is the author of Handbuch des erdmagnetismus (1849).

Biography

Von Lamont was born John Lamont at Corriemulzie near Inverey in Aberdeenshire, Scotland. The son of Robert Lamont (forester to James Duff) and Elizabeth Ewan, his education began at the local school in Inverey, near Braemar. In 1817 his father died and John was sent to be educated at St James' monastery (Scots Benedictine College) at Ratisbon, Germany.[1] He began to work in astronomy and joined the Bogenhausen Observatory, became its director in 1835, took his doctorate of philosophy in 1830 and became professor of astronomy in 1852 at Munich University. At the observatory he undertook the task of creating a star catalog that had about 35,000 entries.

His most important work was on the magnetism of the Earth. He performed magnetic surveys in Bavaria and northern Germany, France, Spain, and Denmark. He discovered a magnetic decennial period (ten-year cycle) and the electric current in the Earth closing the electric "circuit" creating the magnetic field in 1850. This roughly matched the eleven-year sunspot cycle discovered by Heinrich Schwabe.

He calculated the orbits of the moons of Uranus and Saturn, obtaining the first value for Uranus' mass. By chance he observed Neptune in 1845 and twice in 1846, but did not recognize the object as being a new planet.

Lamont is the author of Handbuch des Erdmagnetismus (1849).

He died, single, in Munich, Germany and his considerable wealth was used to found scholarships in sciences.[1]

Honours

His many honours include FRS, FRSE and title of nobility from the King of Bavaria. The statue on his tomb in Munich has him with an open hand, into which the locals put small coins. In 1934 the Deeside Field Club erected a granite memorial cairn in his memory at Inverey, Scotland. It was unveiled by Sir James Jeans.[1]

The following astronomical features were named in his honor:
