James Boswell died in 1795 believing he had touched and kissed a cache of Shakespeare's original letters and papers discovered by a Mr. Ireland. His friend, Edmond Malone, publicly exposed the lot as a forgery just a year later.
Emerich de VattelBorn 1714
Born in Neuchatel, Switzerland, the son of David de Vattel, a minister of the Reformed Church, and his wife, Marie de Montmolin.
Vattel had his general education at the University of Bâle, before continuing on to the University of Geneva, where he specialized in moral philosophy. In 1742 or 1743 he went to Dresden, where his abilities were at once recognised by the Prime Minister, Count de Brühl. He entered the Saxon diplomatic service and over the next years acted as Embassy adviser and minister-plenipotentiary at Berne before being appointed Privy Councillor in 1758.
In 1764 he married Marianne de Chesne, who, on January 31, 1765, bore him a son.
In the last 10 years of his life, De Vattel came to be regarded as an influential philosopher and a legal expert, effectively laying the foundations of modern political philosophy and international law with his 1758 book Droit de Gens (EN: The Law of Nations).1
Life with Boswell:
Boswell waited, with a recommendation from Denis-Daniel de Froment, on Vattel in Dresden, in the evening of October 9, 1764. He was well received and found Vattel “a mild, sensible, pretty man”. Boswell then joined Vattel for the evening at the Danish envoy Count Schulenburg's. They “talked of learning in general, of the late war in Germany, of fate and free will, or more properly the origin of evil”.
