Biography of Johann Gottlieb Friedrich Bonenberg

Johann Gottlieb Friedrich Bonenberg was a German astronomer and mathematician. He was born on June 5, 1765, in the city of Zimocgame (now part of Württemberg).

Early Life and Career

Bonenberg initially pursued a career as a preacher. However, his interests shifted towards mathematical sciences, and he obtained a position at the Tübingen Observatory. In 1803, he was appointed as a professor of mathematics and astronomy at the University of Tübingen.


Bonenberg made significant contributions to trigonometric measurements in Württemberg, particularly in the creation of the Schwabian map consisting of 55 sheets. In his work "Astronomy" (Tübingen, 1811), he provided the first description of the reversible pendulum.

He co-edited the "Tübinger Blätter für Naturwissenschaften und Arzneikunde" (Tübingen, 1815–18) with Autenberg and the "Zeitschrift für Astronomie und verwandte Wissenschaften" with Lindenau.

Bonenberg also improved the electroscope and invented the rotational machine, later known as the "gyroscope," which visually explained the laws of the Earth's rotation around its axis. This machine was introduced in French schools under Napoleon I's orders.

Legacy and Death

Johann Gottlieb Friedrich Bonenberg passed away on April 19, 1831, in the city of Tübingen. In honor of his contributions, a crater on the Moon was named after him.
