Anton van Leeuwenhoek

1632-1723

Dutch microscopist and biologist who was among the first to study biological specimens with a microscope. He is regarded as one of the founders of modern biology. He was first to observe bacteria and protozoa; co-discovered spermatozoa; studied optic lens and red blood cells; observed the fine structure of muscles, nerves, insects, and plants; discovered parthenogenesis; and disproved spontaneous generation. Initially, his interest in microscopes was a hobby, but his observations made him world-renowned.
