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.
Life with Boswell:
Boswell called on a Mr. Craufurd on June 1, 1764, presumably to order some White Port which he had previously promised to send to Abraham Gronovius. According to the editors of Boswell in Holland 1763-64 this Craufurd was Patrick Craufurd, but it may in fact have been his father, James (see James Craufurd for further info).
