Ernest studied for his medical doctorate under the supervision, among others, of botanist and "father of modern taxonomy" Carl Linnaeus (Carl von Linné) who was also President of the Medical Faculty at Uppsala University (3). Ernest's dissertation was entitled "De Haemorrhagiis ex Plethora" (2) (3) and was scheduled for public disputation in the Caroline Auditorium of the University on May 23rd, 1772 (3). At the time, dissertations were an argument for the Praeses' own work (2) - in this case, Carl Linnaeus - and were scheduled in the Spring so that doctoral candidates could graduate by June of the same year (3). For readers of Latin, a PDF scan of Ernest's 1772 dissertation can be downloaded here - it is an essay on bleeding caused by a greater volume of blood in the circulatory sytem than the heart can accommodate and keep in constant circulation. Ernest died at the age of 58, having been paralyzed by a stroke long before (4).
