Georg Christoph Lichtenberg (1742–99) was a German philosopher, physicist, and an important figure in the German Enlightenment. A satirist and writer of aphorisms, he is best known, apart from an experiment in xerographic electricity, for his derision of metaphysical and romantic extravagances.
Born in Ober-Ramstadt, near Darmstadt, State of Hesse, Lichtenberg was crippled by an accident in childhood. He was the 17th child of a Protestant pastor, who trained him in mathematics and the natural sciences. In 1763, Georg entered Göttingen University, where he taught until his death.
Lichtenberg researched geophysics, volcanology, meteorology, chemistry, astronomy, and mathematics. His most important studies were his experimentations into physics. Specifically, he constructed a massive electrophorus in 1777 and discovered the central principle of modern xerographic copying; the images that he reproduced are still termed “Lichtenberg figures.”
A satirist and humorist, Lichtenberg was one of the sharpest intellectuals and prose writers of the eighteenth century. Although Lichtenberg wrote no major creative works, he is well known for his brilliant satire on the Swiss philosopher Johann Kaspar Lavater’s Physiognomische Fragmente, appearing under the title Über Physiognomik, wider die Physiognomen (1778.)
Throughout his adult life, Lichtenberg kept notebooks he called Sudelbücher (“waste books.”) In them, he recorded quotations, sketched, and made brief observations on a variety of subjects from science to philosophy. First published posthumously in 1800–06, they became his best-known work and built his repute as an aphorist. Selections from the Sudelbücher were published in English as The Waste Books (2000.)
