Paul Karl Ludwig Drude (Template:IPAc-en; Script error: No such module "IPA".; 12 July 1863 – 5 July 1906) was a German physicist specializing in optics. He was known for the Drude model.
Biography
Education
Born in Braunschweig, Drude began his studies in mathematics at the University of Göttingen, but later changed his major to physics. His dissertation covering the reflection and diffraction of light in crystals was completed in 1887, under Woldemar Voigt.[1]
Drude graduated the year Heinrich Hertz began publishing his findings from his experiments on the electromagnetic theories of James Clerk Maxwell. Thus Drude began his professional career at the time Maxwell's theories were being introduced into Germany.[2]
Career
In 1894, Drude became an extraordinarius professor at the University of Leipzig; in the same year he married Emilie Regelsberger, daughter of a Göttingen lawyer. They had four children. In 1900, he became the editor for Annalen der Physik, the most respected physics journal at that time. From 1901 to 1905, he was Ordinarius Professor of Physics at Giessen University. In 1905, he became the Director of the Physics Institute of the University of Berlin. In 1906, at the height of his career, he became a member of the Prussian Academy of Sciences. A few days after his inauguration lecture, for inexplicable reasons, he committed suicide. Drude was survived by his wife and children.[1]
Research
His first experiments were the determination of the optical constants of various solids, measured to unprecedented levels of accuracy. He then worked to derive relationships between the optical and electrical constants and the physical structure of substances. In 1894 he was responsible for introducing the symbol "c" for the speed of light in a perfect vacuum.[1]
Toward the end of his tenure at Leipzig, Drude was invited to write a textbook on optics, which he accepted. The book, Lehrbuch der Optik,[3] published in 1900, brought together the formerly distinct subjects of electricity and optics, which was cited by Drude as an “epoch-making advance in natural science.”[1][4]
In 1900, he developed a powerful model to explain the thermal, electrical, and optical properties of matter. The Drude model would be further advanced in 1927 by Arnold Sommerfeld into the Drude–Sommerfeld model.[1]
