Freiherr Adolph Franz Friedrich Ludwig Knigge (16 October 1752 – 6 May 1796) was a German writer, Freemason, and a leading member of the Order of the Illuminati. Knigge was born in Bredenbeck (now a part of Wennigsen, Lower Saxony) in the Electorate of Hanover as a member of the lesser nobility. When he was barely eleven, his mother died, and when his father died three years later the teenager inherited a large debt. His creditors took possession of the family property and assigned the boy a meagre pension of 500 thalers.
