Antony van Leeuwenhoek
A short 100-word "abstract" of this biography: http://www.ucmp.berkeley.edu/history/leeuwenhoek.html for Biology
Antony van Leeuwenhoek was a Dutch tradesman turned scientist. He made some of the best early microscopes which allowed him to make many important discoveries. He was very good at shaping glass and he was able to produce a microscope with 200x magnification. He is sometimes credited with inventing the microscope; however he first saw the idea in books. Although he was not a “real” scientist, he published many articles in scientific journals about his discoveries including bacteria and blood cells and lake water. To this day, he is known as one of the first to have studied the microscopic world up close.
Antony van Leeuwenhoek was an unlikely scientist. Leeuwenhoek was born in Delfton October 24, 1632. A drawing of one of Leeuwenhoek's "microscopes" is shown at the left. Compound microscopes (that is, microscopes using more than one lens) had been invented around 1595, nearly forty years before Leeuwenhoek was born. In 1673, Leeuwenhoek began writing letters to the newly-formed Royal Society of London, describing what he had seen with his microscopes -- his first letter contained some observations on the stings of bees. Leeuwenhoek looked at animal and plant tissues, at mineral crystals and at fossils. Leeuwenhoek soon became famous as his letters were published and translated.
