  Notes	Leopold Pfaundler von Hadermur (14 February 1839 - 6 May 1920) was an Austrian physicist and chemist born in Innsbruck. He was the father of pediatrician Meinhard von Pfaundler (1872-1947), and the father-in-law of pediatrician Theodor Escherich (1857-1911). He studied under chemist Heinrich Hlasiwetz (1825-1875) at Innsbruck, with Justus von Liebig (1803-1873) at the University of Munich, and with Henri Victor Regnault (1810-1878) and Charles Adolphe Wurtz (1817-1884) in Paris. In 1861 he received his doctorate, and in 1867 was appointed professor of physics at the University of Innsbruck. In 1891 he succeeded Ludwig Boltzmann (1844-1906) as professor of physics at the University of Graz. In 1887 he became a full member of the Vienna Academy of Sciences. Pfaundler is remembered today for his kinetic-molecular explanation of gas reactions under the condition of equilibrium. He was the inventor of a number of scientific apparatuses - devices he often utilized in classroom demonstrations. These included a temperature regulator (1863), a Stromkalorimeter (1869), a differential air thermometer (1875), a seismograph (1897) and a distance meter (1915), to name a few. He is also credited with creating a device for optical demonstration of Lissajous figures (1873). In 1863-64 he performed a survey of the Stubaier Alps with Ludwig Barth zu Barthenau (1839-1890), and in 1864 he was the first person to ascend to the summit of the Hofmannspitze (3112m). Pfaundler was active in several scientific societies and also served as Rector of the University of Innsbruck in 1880. He was an avid mountain climber and photographer of mountain landscapes, for which he received a silver medal at the 1901 International Photographic Exhibition, as well as an early enthusiast of the Japanese game of Go on which he published a book in 1908. Other interests included ecology and the carrying capacity of the earth and advocacy of an artificial international language for use in the scientific literature. Indeed, in 1914 he published a photographic lexicon in Ido, a simplified version of Esperanto. He died in Graz in May of 1920 at age 81. Leopold, university professor of physics at the University of Innsbruck in 1891, received a professorship at the University of Graz. There Hermann visited the High School and studied at the University of Graz. He received his doctorate in 1904 from Dr. iur. and then was in the Styrian service as an official. After temporary use in the Central Statistical Commission in Vienna, he came into the k. k. Telegraph Correspondence-Bureau. In 1916, he was assistant director; he was a delegate of the 1917/1918 Bureau in the peace negotiations at Brest-Litovsk in 1933, and in 1926 he took over the management of the official news agency (formerly Burau). After that, he was undersecretary and Section Head of the chancellor's office. The summer months Pfaundler held regularly in Tyrol, was an avid mountaineer and made several first ascents. Received the title of nobility with the title "von Hadermur" on 9 Nov 1910
