Oldenburg translated the early letters, and he was the one who first translated dierkens as "animalcules". On the graph above, that's the small blue blip around 1670. During his life he made more than 500 lenses and some twenty-five different microscopes. His researches on lower animals refuted the doctrine of spontaneous generation, and his observations helped lay the foundations for the sciences of bacteriology and protozoology. What is the role of DNA? Van Leeuwenhoek’s discovery of “animalcules”, “I then most always saw, with great wonder, that in the said matter there were many very little living animalcules, very prettily a-moving. 1 synonym for animalcule: animalculum. He even scraped plaque from his own teeth and observed it under the microscope. At the age of 16, he worked as a bookkeeper at a linen-draper's shop in Amsterdam. The existence of microscopic organisms was discovered during the period 1665-83 by two Fellows of The Royal Society, Robert Hooke and Antoni van Leeuwenhoek. He discovered single-celled plants and animals (1674), red blood cells (1674), spermatozoa (1677 – later concluding that eggs were fertilized when entered by sperm), the pattern of muscular fibers (1682), the lymphatic capillaries (which contained a white milky fluid -1683), and the interior of the coffee bean (1687). Helped by his business experience in Amsterdam, he opened his own textile and haberdasher shop, selling cloth but also such items as buttons and ribbons.
