Antonie van Leeuwenhoek- Improving the microscope
Antonie Van Leeuwenhoek was known for improving the microscope and was considered the first microbiologist. How he improved the microscope was he would take a small rod of glass and put it in the hot flame to create two glass whiskers, after he would re-ensert one of the whiskers to make a small sphere and that sphere would become the lenses of the microscope. The smaller the lense the more magnification it would have. -
