Samuel Freiherr von Pufendorf was a German jurist, political philosopher, economist and historian. He was born Samuel Pufendorf and ennobled in 1694; he was made a baron by Charles XI of Sweden a few months before his death at age 62. Among his achievements are his commentaries and revisions of the natural law theories of Thomas Hobbes and Hugo Grotius.
His political concepts are part of the cultural background of the American Revolution. Pufendorf is seen as an important precursor of Enlightenment in Germany. He was involved in constant quarrels with clerical circles and frequently had to defend himself against accusations of heresy, despite holding largely traditional Christian views on matters of dogma and doctrine.
