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.
Jerome David Gaubius
Jerome David GaubiusBorn 1705
Died Nov 29, 1780
A student of Boerhaave's1 and his succesor as Professor of Medicine and Chemistry at Leyden. Gaubius was much respected in his time, and his Libellus de Methodo Concinnandi Formulas Medicamentorum (1739) was translated into English as early as 1741. One of his best known works was Institutiones Pathologiae medicinalis (1758), a textbook on systematic pathology which remained popular for many years.
Boswell visited Gaubius in Leyden on May 5, 1764. In the autumn of 1763 Boswell had left a chemical preparation of his uncle's with Gaubius, without actually meeting the doctor. On May 4 or 5 he wrote a letter to Gaubius in latin, asking to meet him, which he did.
Note 1: Herman Boerhaave (1668-1738) was a Dutch botanist, humanist and physician of European fame. He is regarded as the founder of clinical teaching and of the modern academic hospital. His main achievement was to demonstrate the relation of symptoms to lesions. (Source: Wikipedia)
