Biography of Georg Christoph Lichtenberg

Georg Christoph Lichtenberg, an outstanding German scientist and satirist, is remembered today as the person who introduced the use of '+' and '-' to denote positive and negative electrical charges, thereby eliminating the confusion that existed before him in the description of electricity. In 1777, he also observed and described the phenomenon known as "Lichtenberg figures".

Early Life and Education

Georg Christoph Lichtenberg was born on July 1, 1742, as the youngest of seventeen children of Pastor Johann Conrad Lichtenberg. His father, through his career in the church, eventually attained a leadership position in Darmstadt, Germany. It was unusual for a clergyman of that time to possess significant scientific knowledge, and it is believed that Georg inherited his intellectual curiosity from his father.

Georg Christoph Lichtenberg received homeschooling until the age of ten, after which he attended a local school. His intelligence and wit became evident at a very young age. Georg had a strong desire to study mathematics, but his family could not afford to pay for lessons. In 1762, his mother appealed to Ludwig VIII, the Landgrave of Hesse-Darmstadt, and Ludwig provided funds for the education of the talented young man. In 1763, Lichtenberg enrolled at Göttingen University and by 1769, he became a physics lecturer. Six years later, he obtained a professorship, which he held until his death.

Scientific Contributions and Relationships

Due to a spinal condition, Lichtenberg developed a hunchback, which resulted in him having an unusually short stature even by eighteenth-century standards. Over time, his condition caused increasing discomfort and impacted his breathing. Nevertheless, Lichtenberg remained highly respected and popular in European intellectual circles, constantly introducing innovations. He was one of the first physicists to conduct experiments using apparatus during lectures. He maintained friendly relationships with many prominent figures of the time, including Goethe and Kant.

In 1784, the renowned Italian physicist Alessandro Volta visited Göttingen solely to meet Lichtenberg and witness his experiments. The famous mathematician Carl Friedrich Gauss was one of his lecture attendees. In 1793, Lichtenberg was elected a member of the Royal Society in London. He was one of the first in Germany to apply Benjamin Franklin's lightning rod, installing it on his house in Göttingen and in the garden.

Lichtenberg's principles of xerography paved the way for modern copying machines. He also proposed a system of paper size standards, known as ISO 216, which is used worldwide except in the United States and Canada, and is based on the A4 size as the most commonly used. At the invitation of his students, Lichtenberg visited England twice in 1770 and 1774-1775, where he was warmly received by George III and Queen Charlotte. Great Britain made such a positive impression on him that he became known as an anglophile.

Personal Life and Legacy

Despite his physical limitations, Lichtenberg was known for his romantic involvements and had numerous affairs, mostly with women from less affluent families. In 1777, he met Maria Stechard, who was 13 years old at the time, and she became his companion in 1780. She passed away in 1782. The following year, he met 15-year-old Margarethe Kellner and married her in 1789, primarily for her pension (as Lichtenberg believed he would soon die). Margarethe gave birth to six children and outlived him by 49 years. On February 24, 1799, Lichtenberg passed away after a brief illness at the age of 56.
