Royal Society fellows couldn't believe it.Even with his most powerful instruments,the celebrated English microscopist Robert Hooke had never observed anything like the little creatures.
In fact,the Dutchman had developed far superior lenses to Hooke's,and had discovered bacteria and protozoans (原生动物).By producing even smaller and more curved lenses—using a technique that he kept secret—van Leeuwenhoek was able to magnify objects up to 500 times.As well as discovering microorganisms,he was the first to see red blood cells.
In 1677,van Leeuwenhoek
sent the Society further animalcule observations.Hooke eventually improved his own microscopes to the point where he,too,could see the tiny creatures.Three years later van Leeuwenhoek was made a fellow.
It was not until 1890,more than 160 years after van Leeuwenhoek's death,that bacteria were linked with diseases.“Reading van Leeuwenhoek's letters,you very much get the impression of somebody dazzled by what he was finding,”says Lesley Robertson,leader of the archives at Delft University's school of microbiology.“He thought he'd found a whole new world—but he certainly never picked up on the connection with illness.”
