Frequently asked questions

The key thing to remember is that Herman Boerhaave (1668-1738) was not merely a Dutch physician, but a true institution. A professor at the University of Leiden, he simultaneously held the chairs of medicine, botany, and chemistry, which was extremely rare at the time. What makes him unique is that he transformed medical teaching by taking students out of the lecture halls and bringing them directly to the patients' bedside, thus founding modern clinical medicine. His reputation became so great that it is said a letter addressed simply "To the illustrious Boerhaave, physician, in Europe" reached him without difficulty.

Anecdotes

Herman Boerhaave became so famous throughout Europe that, the story goes, a letter addressed “To the illustrious Boerhaave, physician, in Europe” reached him without any difficulty. Patients came from Russia, England and even Asia to consult him.

When he died, a mysterious and beautifully bound book was found among his papers, titled “The One and Only Secret of Medicine.” All its pages were blank, except one that bore these words: “Keep your head cool, your feet warm and your bowels open, and you will laugh at all the doctors.”

Boerhaave taught at the bedside of the sick, in the wards of the Saint Cecilia hospital in Leiden, where only twelve beds were set aside for his lessons. This revolutionary way of learning medicine “at the patient's bedside” made Leiden the medical capital of Europe.

Tsar Peter the Great of Russia, while travelling through the United Provinces, was absolutely determined to meet Boerhaave. Unable to see him during the day because of the crowds, he is said to have waited for him very early in the morning, sitting on a bench, to discuss medicine and botany with him.

Boerhaave directed the botanical garden of Leiden and enriched it considerably, growing it from a few hundred to several thousand species. He exchanged plants and seeds with scholars from all over the world to expand this living collection.
