Ford says the pictures are the first to do justice to the clarity of images available with Leeuwenhoek microscopes. Alexander Fleming. He made the important first discovery of microorganisms, which he viewed as small animals, animalcules. Similar experiments in the eighteenth century were not always successful because of difficulties the workers experienced in making simple lenses as effective as those used by van Leeuwenhoek. Ford wanted to experience what Leeuwenhoek had observed so he had a device built that effectively used the tiny lenses in authentic or replica Leeuwenhoek microscopes as the lenses for his own camera, and started to take photos. What are synonyms for animalcules? All the main kinds of unicellular organisms that we know today – protozoa, fungi, algae, & bacteria were first described by Leeuwenhoek. But he admits the devices are difficult and fiddly to use. . At the age of 16, he worked as a bookkeeper at a linen-draper's shop in Amsterdam. The other pictures were taken with a replica microscope. The first observation on Saturday, July 24, had been inconclusive, so Leeuwenhoek ordered more rams' testicles to continue his observations.On Tuesday, July 27, he found "clouds" of sperm, which he described with astonishment.The following morning, he checked again.

Animalcules Discovered: Antony van Leeuwenhoek, 1632–1723, was a Dutch student of natural history and maker of microscopes.
