Dr. Ernst Freiherr von Bibra (9 June 1806 in Schwebheim – 5 June 1878 in Nuremberg) was a German Naturalist (Natural history scientist) and author. Ernst was a botanist, zoologist, metallurgist, chemist, geographer, travel writer, novelist, duellist, art collector and trailblazer in ethnopsychopharmacology.
Ernst's father, Ferdinand Johann von Bibra, (*1756; † 1807), fought under General Rochambeau in the American Revolutionary War on behalf of the colonies. Later he married his brother's daughter, Lucretia Wilhelmine Caroline von Bibra,(1778. + 1857). Ernst's father died when he was 1½ years old and Baron Christoph Franz von Hutten (d. 1830) raised Ernst in Würzburg. He graduated at nineteen from a boarding school in Neuberg on the Danube. Baron Ernst von Bibra started studying law at Würzburg but soon changed over to the natural sciences, especially chemistry. ("Dr. med. & phil." Doctor of medicine & PhD) Martin Haseneier, in his Foreword to the 1995 translation Plant Intoxicants relates that Ernst fought in no less than 49 duels as a young man! Six of his works have been reprinted in recent years. Besides the castle and estate at Schwebheim, Ernst was the owner of a half interest in the castle and estate at Willershausen (Herleshausen). Ernst sold his half of the castle and estate of Willershausen (Herleshausen) in 1850 to the Landgrave Carl August of Hesse.
The Bibra family was one of the leading Uradel (ancient noble) families in Franconia (northern part of Bavaria) and Thuringia from the mid-15th century to about 1600. Later on the family rose from Reichsritter (Imperial Knights) to Reichsfreiherr (Barons of the Holy Roman Empire). After the Holy Roman Empire dissolved, they were made ‘’Freiherr’‘ (Barons) of Bavaria and Bohemia.
The earliest references to the family include a document of Bishop Otto of Bamberg from the year 1119 of a Rupertus de Bibra. In 1151 a Pertholdus (Berthold) de Bibra and his sons Pertholdus (Berthold) and Tagino are referenced in another document. The family prospered in numbers, wealth, and influence in the 15th century and early 16th century. By the time of Siebmachers Wappenbuch of 1605, the family is listed as the most important family of Franconia under the rank of Freiherr. By 1600 most of the family died off without heirs partially due natural causes such as the Bubonic plague and the number of family members who took church positions. After the death of Heinrich von Bibra in 1602, the Prince-Bishop Julius Echter von Mespelbrunn seized most of the family’s assets as part of the Counter-Reformation resulting in a 79 year lawsuit. The lawsuit (Reichskammergericht) was eventually settled with the family receiving all the properties except Burgwallbach but without income during the suit. From 1602 on there were many important members of the family but the family itself never recovered the leading position it previously had in the late 15th and 16th centuries. Between 1698 and 1772, the various lines were raised to Reichsfreiherr (Barons of the Holy Roman Empire). In later times, the family spread to the Austrian Empire, the British Empire, and the United States. According to Wagenhöfer, the Bibra family is the most researched family of the low nobility in Franconia after the Guttenberg and Seckendorff families.
