Reproductions and descriptions of Dutch, Italian and British early microscopes:-
Antonie Philips van Leeuwenhoek (October 24, 1632 – August 26, 1723) was a Dutch tradesman and scientist. He is commonly known as "the Father of Microbiology", and best known for his work on the improvement of the microscope. Using his handcrafted microscopes, he was the first to observe and describe microorganisms, which he originally referred to as animalcules (from Latin animalculum = "tiny animal"). Van Leeuwenhoek did not author any books; his discoveries came to light through correspondence with the Royal Society, which published his letters. By the end of his life, Van Leeuwenhoek had written approximately 560 letters to the Royal Society and other scientific institutions concerning his observations and discoveries.
In 1981 the British microscopist Brian J. Ford found that Van Leeuwenhoek's original specimens had survived in the collections of the Royal Society of London. They were found to be of high quality, and were all well preserved. Ford carried out observations with a range of single-lens microscopes, adding to our knowledge of Van Leeuwenhoek's work
