Johann Georg Estor (6 June 1699 – 25 October 1773), was a German theorist of public law, historian and book collector.
As professor in Giessen he learned natural history from his colleague Joahnn Melchior Verdrieß and became national geographer of the county of Hessen-Darmstadt.
In his early work Auserlesene kleine Schrifften there are several articles by himself and by other authors in which it is proven that the bondage of the peasants, which was in practise at his time, meant nothing more or less than slavery.
But to Estor's point of view this chapter 5 was typical for the democratic character of the Holy Roman Empire and for the role of the Kaiser as the first Representative of the Reichsversammlung.
[citation needed] Contrary to the legend, that this powerful pope stemmed from the noble family Aldobrandeschi, Estor claims, that he was the son of a blacksmith in Saona in the Italian county of Toscana and that his full name was Hildebrand Bonizi.
In the second volume of his "neue kleine Schriften", pages 195/6, there is a little note, in which Estor says that he had explored the landscapes of Hessen-Darmstadt on horseback or walking to accomplish a book about the national geography of this county.
