Description:
(Dutch Biologist and Microscopist Who Was the First to Observe and Describe 'Red Blood Cells') Dutch naturalist Jan Swammerdam was the first to detect red blood cells. Though a qualified doctor, he never practiced medicine, and took to research instead. Known for his research on anatomy, he also revolutionized the study of insects, proving that the egg, larva, pupa, and adult are all the same organism.
