  1. Maybe not 1942 for Leeuwenhoek [LINK]:

    Antoni van Leeuwenhoek is widely credited as the discoverer of red blood cells. In truth, he was not the first person to observe "red particles" in blood but his observations were more detailed and numerous than those (by Malpighi and Swammerdam) that preceded him .

    1) Antoni van Leeuwenhoek (1632-1723)

    Leeuwenhoek's first written description of human red blood cells (his own) was in a letter to Constantine Huygens (father of the physicist and astronomer Christiaan Huygens) on April 5, 1674 and later in another letter addressed to Mr. Oldenberg, Secretary of the Royal Society of London on April 5, 1674. The first publication of the observation of globules in blood occurred in April 1674 in the Philosophical Transactions of the Royal

    Society of London in which Leeuwenhoek published his 1673 observations reported in the letter to Huygens (see Figure). In a letter dated August 14, 1675, Leeuwenhoek went on to make the remarkable discovery that "those sanguineous globules in a healthy body must be very flexible and pliant, if they are to pass through the small capillary veins and arteries, and that in their passage they change into an oval figure, reassuming their roundness when they come into a larger room."[END QUOTE]
