Born at Freiwaldau, now Jeseník, a town in the Olomouc Region of the Czech Republic in August of 1837, Edmund Weiss was a professor and
astronomer who became the director of the Vienna Observatory in 1878, a post he held until his retirement in 1910.
Born to hydrotherapy pioneer Josef Weiss and his wife, Edmund Weiss was the twin brother of noted botanist Adolf Gustav Weiss, Professor of Botany at Prague. Edmund Weiss spent his early years in Richmond, England where his father was the director of the hydrotherapy center at Stansteadbury in Hertfordshire. After his fathers death in 1847, Josef Weiss returned to his native land where he studied at the Gymnasium in Troppau, now Opava, from 1847 to 1855. He continued his education at the Vienna University with studies in mathematics, astronomy and physics.
On the completion of his studies, Weiss was appointed an assistant at the Vienna Observatory in 1858. While employed at the observatory, he continued his studies and was awarded in 1860 the degree of Doctor of Philosophy. As an assistant, Weiss was a diligent and skilled observer; he was noted for his accuracy in the measurement of a meridian arc during the period of 1864 to 1867. Although offered positions by astronomer Otto
Wilhelm von Struve at the Pulkovo Observatory in Petrograd and chemist Adolf von Baeyer at Berlin’s Geodetic Institute, Weiss remained in Vienna where he received the title of honorary professor in 1869 and, in 1875, a full professorship.
In 1872, Edmund Weiss visited England and North America in order to study the leading observatories and new developments in optical works. The knowledge he gained was utilized at the building of a new observatory in the Vienna district of Währing as well as the purchase of its new instruments, among which were the 1882 twenty-seven inch equatorial by Dublin’s Grubb Telescope Company and an eleven three-quarter inch equatorial by Alvan Clark & Sons of Cambridgeport, Massachusetts. The construction of the Währing observatory was overseen by its director Karl Ludwig Littrow who died before the observatory’s completion. Weiss was appointed its new Director in 1878 and retained that post until 1910 when he retired with the title Emeritus Director.
The detailed observations at the Währing Observatory were related to the planets, comets, occultations (the concealment of celestial bodies by another), variable stars and meteors. From these studies, Weiss published a large number of papers among which were those that examined the connection between comets and meteors, the meteor swarm of Halley’s Comet, the magnitude of minor planets, the nebulae in the Pleiades, and a method of obtaining True Anomaly and the radius vector of great
orbital eccentricity. He published a new edition of astronomer Joseph Johann von Littrow’s popular “Die Wunder des Himmels (The Wonders of Heaven)” and, in 1890, a revised edition of Wilhelm Albrecht Oeltzen’s 1857 astronomical catalogue “Argelander’s Southern Zones”. Weiss also published a pictorial atlas of astronomy in German, the 1888-1892 “Bilderatlas der Sternenwelt (Stellar Atlas)”.
Edmund Weiss made multiple journeys to observe astronomical phenomena, particularly eclipses. He observed the 1861 eclipse in Greece, that achieved just total before sunset; the 1867 annular (ring) eclipse from Dalmatia, Croatia; the 1868 total eclipse from Eden, Ireland; the total eclipse of 1870 from Tunis, Tunisia; and the 1874 Transit of Venus, the first of two transits in the nineteenth- century, from Jassy, Romania. These eclipse expeditions led to Weiss’s interest in solar physics and his membership with the International Union for Solar Research.
Weiss developed a high reputation in Vienna as a lecturer on astronomy. He was elected a Fellow of the Vienna Academy in 1878 and an Associate of the Society in 1883. Awarded the Bessemer Gold Medal in 1883, Edmund Weiss died at the age of seventy-nine in June of 1917 after a long and painful illness. He was survived by his wife Adelaide Fenzl and seven children. The “Weiss” lunar crater along the southern edge of the Mare Nubium was named after him.
Notes: It should be noted that Edmund Weiss is not the illustrator for the “Bilderatlas der Sternenwelt”. If anyone locates the name of the artist, please make a note in the comment section.
An annular eclipse occurs when the Moon passes directly between the Earth and the Sun but does not completely cover the Sun’s disk, leaving the outer edge visible as a bright ring around the Moon.
