- Lichtenberg, Georg Christoph
▪ German philosopher and physicistborn July 1, 1742, Ober-Ramstadt, near Darmstadt, Hesse [Germany]died Feb. 24, 1799, Göttingen, HanoverGerman physicist, satirist, and writer of aphorisms (aphorism), best known for his ridicule of metaphysical and romantic excesses.Lichtenberg was the 17th child of a Protestant pastor, who taught him mathematics and natural sciences. In 1763 he entered Göttingen University, where in 1770 he became assistant professor of physics and in 1775 professor. This post he held until his death. Lichtenberg did research in a wide variety of fields—including geophysics, volcanology, meteorology, chemistry, astronomy, and mathematics—but most important were his investigations into physics. Notably, he constructed a huge electrophorus and, in the course of experimentations, discovered in 1777 the basic principle of modern xerographic copying (electrophotography); the images that he reproduced are still called “Lichtenberg figures.”As a satirist and humorist Lichtenberg takes high rank among the German writers of the 18th century. His biting wit involved him in many controversies with well-known contemporaries, such as Johann Kaspar Lavater (Lavater, Johann Kaspar), whose science of physiognomy he ridiculed, and Johann Heinrich Voss (Voss, Johann Heinrich), whose views on Greek pronunciation called forth a powerful satire, Über die Pronunciation der Schöpse des alten Griechenlandes (1782; “On the Pronunciation of the Muttonheads of Old Greece”). In 1769 and again in 1774 he resided for some time in England, and his Briefe aus England (1776–78; “Letters from England”) are the most attractive of his writings. He contributed to the Göttinger Taschenkalender (“Göttingen Pocket Almanac”) from 1778 onward and to the Göttingisches Magazin der Literatur und Wissenschaft (“Göttingen Magazine of Literature and Science”), which he edited for three years (1780–82) with J.G.A. Forster. He also published in 1794–99 an Ausführliche Erklärung der Hogarthschen Kupferstiche (“Full Explanation of Hogarthian Copper Engravings”).From 1765 until the end of his life, Lichtenberg kept notebooks he referred to as Sudelbücher, or “waste books,” where he recorded quotations, sketched, and made brief observations on a wide range of subjects from science to philosophy. First published posthumously in 1800–06, they became his best-known work and gave him his reputation as an aphorist. Selections from the Sudelbücher were published in English as The Waste Books (2000).
