Johann Gottlieb Siegel (25 April 1699 - 1755) was a German legal scholar. Life 
Gottlieb was born on 25 April 1699 in Klosterhäseler, Saxony-Anhalt, the son of Pastor Johann Georg Siegel (1692-1728) and his wife Amanda Helen Elizabeth, daughter of Johann Gottfried Schuchardt, the Auditor of the dragoons . He attended the Gymnasium Illustre Augusteum in Weissenfels, returning home in 1714. In 1717, he moved to the University of Leipzig where he attended lectures by Gottfried Polycarp Müller (1685-1747), Lueder Mencke (1658-1726), Johann Christoph Schacher (1667-1720) and Karl Otto Rechenberg (1689-1751). For further studies he went to the University of Wittenberg. The teachers at that time included Karl Jakob Spener (1684-1730), Johannes Balthasar Wernher, Heinrich Christoph Berger, Christian Basti Gebhard Neller, Gottfried Ludwig Mencke the Elder and Michael Heinrich Gribner 
In Wittenberg, on 29 June 1719 he acquired the Licentiate of the rights, and on 26 August 1720 he graduated as a Doctor of Law. In 1734 Siegel was an attorney in Leipzig, Saxony at the Leipzig Consistory (for church matters) and the Oberhofgericht (Saxon Supreme Court). On 9 February 1735 he became Professor of feudal law at the Law Faculty of the University of Leipzig, and 1740 he became Counsel of the Leipzig merchants. He was general counsel of the University in 1741 and in the winter semester 1753/54 he was president of the Alma Mater.
