Georg Christoph Lichtenberg was a German physicist, satirist, and Anglophile. As a scientist, he was the first to hold a professorship explicitly dedicated to experimental physics in Germany. He is remembered for his posthumously published notebooks, which he himself called Sudelbücher, a description modelled on the English bookkeeping term "waste books" or "scrapbooks", and for his discovery of tree-like electrical discharge patterns now called Lichtenberg figures.

A waste book was one of the books traditionally used in bookkeeping. It consisted of a daily diary of all transactions in chronological order. It differs from a daybook in that only a single waste book is kept, rather than a separate daybook for each of several categories. The waste book was intended for temporary use only; the information needed to be transcribed into a journal in order to begin to balance one's accounts. The name of the book derives from the fact that, once its information was transferred to the journal, the waste book was unneeded.
