The discovery of blood cells in the human body paved the way for advanced studies in cell biology. Early discovery of genes in volved in human development by Edward Lewis, Christine Nusslein and Eric Wieschaus in 1995 is a clear demonstration of the importance of microscopes in the life sciences.
He coined the term âcellâ when looking at a piece of cork under 30x magnification. In the late 1660s, Antony van Leeuwenhoek began to grind his own lenses and make simple microscopes. Each microscope was really a powerful magnifying glass rather than a compound microscope. Leeuwenhoekâs hand-ground lenses could magnify an object up to 200 times! He observed animal and plant tissue, sperm cells and blood cells, minerals, fossils, and much more. He also discovered nematodes and rotifers (microscopic animals), and he discovered bacteria while looking at samples of plaque from his own and othersâ teeth. 1700-1800s: Not much change in the basic microscope design occurred, but better lenses were crafted (using purer glass and different shapes) to solve problems like color distortion and poor image resolution.
