Gustav Adolph Ackermann
Gustav Adolph Ackermann was a German lawyer and author of a notable book on European knightly orders.
Ackermann was born in Auerbach in Vogtland, Electorate of Saxony, Holy Roman Empire. He was Königlich Sachsischer Appelationsrat at the courthouse in Dresden, Saxony and a great connoisseur of the 19th-century and medieval German and European knightly orders.
In 1855 his Ordensbuch appeared in Annaberg with the subtitle Sämtlicher in Europa blühender und erloschener Orden und Ehrenzeichen . Despite its title, the book is not a complete description of orders and decorations, but it is a valuable resource for researchers.
As a lawyer he also published in his field. In 1849 his Rechtssätze aus Erkenntnissen des Königl. Oberappelationsgerichts zu Dresden, a work on the then applicable jurisprudence, appeared in Saxony. He died in Dresden on February 19, 1872.
