August Rauber (March 9, 1841 – February 16, 1917) was a German anatomist and embryologist born in Obermoschel in the Rhineland-Palatinate.
Rauber was born the fourth of five children to Stephan Rauber and Rosalie née Oberlé. He studied medicine in Munich, obtaining his doctorate in 1865. At Munich his instructors included Theodor Bischoff (1807–1882), Nicolaus Rüdinger (1832–1896) and Julius Kollmann (1834–1918).
Julius von Michel (5 July 1843 – 29 September 1911) was a German ophthalmologist born in Frankenthal.
He studied at the Universities of Würzburg and Zurich, and in 1866 served as a military physician in the Austro-Prussian War. From 1868 to 1870 he was an assistant to Johann Friedrich Horner (1831–1886) at the University Eye Clinic in Zurich. During the Franco-Prussian War (1870–71), he again served as a military doctor, and afterwards worked with Gustav Schwalbe (1844–1916) at Carl Ludwig's Physiological Institute in Leipzig.
In 1872 he earned his habilitation in Leipzig, and subsequently became an associate professor of ophthalmology at the University of Erlangen, where in 1874 he gained a full professorship. In 1879 he was named successor to Robert von Welz at the ophthalmology clinic in Würzburg, and later on, he was a replacement for Karl Ernst Theodor Schweigger at the University of Berlin (1900).
Michel is remembered for work involving tuberculosis of the eye, and his pioneer research of central retinal vein occlusion.Among his written efforts are Lehrbuch der Augenheilkunde (Textbook of ophthalmology, 1890) and Klinischer Leitfaden der Augenheilkunde (Guide to clinical ophthalmology). With Hermann Kuhnt (1850–1925), he founded the journal Zeitschrift für Augenheilkunde.
Wilhelm Heinrich Erb (30 November 1840 – 29 October 1921) was a German neurologist. He was born in Winnweiler, and died in Heidelberg.
Johannes Wilhelm "Hans" Geiger (; German: [ˈɡaɪɡɐ]; 30 September 1882 – 24 September 1945) was a German physicist. He is best known as the co-inventor of the detector component of the Geiger counter and for the Geiger–Marsden experiment which discovered the atomic nucleus. He also carried the Bothe–Geiger coincidence experiment that confirmed the conservation of energy in light-particle interactions.
He was the brother of meteorologist and climatologist Rudolf Geiger.
