The fly His letter on the flea, in which he not only described its structure but traced out the whole history of its metamorphosis, beginning with its first emergence from the egg, is of great interest, not so much for the exactness of his observations as for illustration of his opposition to the spontaneous generation of many lower organisms, such as “this minute and despised creature.
He argued that the sea mussel and other shellfish were not out of sand found at the seashore or mud in the beds of rivers at low water but from spawn, by the regular course of generation.
He finally succumbed to his illness on the 26th August at the grand age of Starting from the assumption that life and motility are identical, he concluded that the moving object that he saw through his microscope were little animals.
For these animalcules can be carried over by the wind, along with the bits of dust floating in the air. His contemporary Robert Hookean early microscope pioneer, bemoaned that the field had come to rest entirely on one man’s shoulders. He was drawn to the investigation of animal reproduction when Stephen Ham of Arnhem, a medical student, told him that he had seen animalcules in human seminal fluid.
Chamberlayne, May 17, Little is known of Leeuwenhoek’s early life, but it is certain that he did not have an extensive scientific education. As more of his works began to get published his repertoire increased exponentially; he was visited by many eminent personalities throughout his lifetime which include the likes of Russian Tsar Peter the Great, German philosopher Gottfried Wilhelm Leibniz and Prince William III of England.

In addition to the pension that it gave him, the municipality of Delft made him special awards upon the publication of several of his books. Although he himself could not draw well, he hired an illustrator to prepare drawings of the things he saw, to accompany his written descriptions.

Antonie van Leeuwenhoek made more than optical lenses.
He actually measured the multiplication of the bugs. In his observations on rotifers inLeeuwenhoek remarked that in all falling rain, carried from gutters into water-butts, animalcules are to be found; and that in all kinds of water, standing in the open air, animalcules can turn up.
Leeuwenhoek first described the individual plant cell, the individual striped muscle cell, spermatozoa, red corpuscles,a and the crystalline lens of the eye. Events of the first half of van Leeuwenhoek’s life. He maintained the same to be true of the freshwater mussel, whose embryos he examined so carefully that he was able to observe how they were consumed by “animalcules,” many of which, according to his description, must have included ciliates in conjunction, flagellates, and the Vorticella.
So good was the magnification, in fact, that he was able to see objects as small as 1. Of course today we know that bacteria leeuwenhoej in a variety of shapes from the classic rod-shaped to spherical and even curved.
Eventually, in the face of van Leeuwenhoek’s insistence, the Royal Society arranged for Leewuenhoek Petrie, minister to the English Reformed Church in Delft; Benedict Haan, at that time Lutheran minister at Delft; and Henrik Cordes, then Lutheran minister at the Hague, accompanied by Sir Robert Gordon and four others, leeuwenhodk determine whether it was in fact van Leeuwenhoek’s ability to observe and reason clearly, or perhaps, the Royal Society’s theories of life that might require reform.
