Georg Christoph Lichtenberg (July 1, 1742 - February 24, 1799), German scientist. He was the first to hold a professorship explicitly dedicated to experimental physics in Germany. He is remembered for his investigations in electricity, and for discovering branching discharge patterns on dielectrics now called Lichtenberg figures. By discharging a high voltage point near an insulator, he was able to record strange tree-like patterns in fixed dust. These Lichtenberg figures are considered today to be examples of fractals. He is also remembered for his posthumously published notebooks. They reveal a critical and analytical way of thinking with an emphasis on experimental evidence in physics, through which he became one of the early founders and advocates of modern scientific methodology.
