❗HISTORY OF PLATELET DISCOVERY. ✅In 1842 in France, Alfred Donné (1801–1878), a medical professional at the Ministry of Health, discovered the third element of blood — platelets. Donné was an avid microscopist. ✅He became known after demonstrating that microorganisms — trichomonads, which he found in vaginal secretions — were responsible for frequent (occupational) infections among Parisian prostitutes. ✅From other microscopists, he heard that blood smears also often contained small dust particles that sometimes blurred the image and should be considered dirt. ✅Through a series of precise observations, Donné was able to prove that these were very small (less than a micron, or one millionth of a meter) flat cells without a nucleus, but containing small granules. 👉Source: Marc Boogaerts - The History of Blood.
