Paul-Ferdinand Gachet's unpublished manuscript. Ophthalmia in the armies of Europe

Paul-Ferdinand Gachet was a close friend and physician of many famous artists who lived in France toward the end of the 19th century. He was van Gogh's last physician, and Vincent painted Gachet's portrait on two occasions. The first of these paintings has become the most expensive painting ever sold at a public auction. Gachet's manuscript on the subject of military ophthalmia has never been published. Only one copy is known to exist. Although the content of the manuscript is not exceptional, Gachet's significance makes dissemination of his writing important.
