Van Leeuwenhoek's letters to the Royal Society, 1704. Dutch scientist Antonie van Leeuwenhoek (1632-1723) built his own microscopes, grinding the lenses himself, according to a single lens design that could magnify up to nearly 200 times. He was able to study the natural world in greater detail than was previously possible. His observations included protozoa, bacteria, insects, plants, minerals, blood cells, and sperm. His earliest observations were published in 1673, and over the next 50 years van Leeuwenhoek self-published and wrote hundreds of letters to learned societies detailing his discoveries. However, most, including the Royal Society, edited and abridged his letters, leading him to publish the full versions in collections such as this one, titled 'Vervolg der Brieven' (1704, third edition). | |
