Antonie van Leeuwenhoek is known for being the first person to discover objects through a microscope. He was a Dutch scientist who lived during the 17th century. He crafted his own microscopes with a single lens, which he used to observe tiny creatures and objects. He discovered single-celled organisms called protozoa, as well as bacteria in a drop of water. He also examined lice and fleas, and observed red blood cells for the first time.
Robert Hooke
Robert Hooke was a British scientist who lived during the 17th century. He is perhaps most famous for his studies of cells and his book “Micrographia,” which contained detailed illustrations of organisms and objects observed through a microscope. He worked with an early compound microscope and discovered the cell structures of plants, cork, and also hair. He coined the term “cell” to describe the chambers he saw in cork under the microscope, and his work helped to develop the field of biology.
Marcello Malpighi
Marcello Malpighi was an Italian scientist who lived during the 17th century. He is known for his discoveries about the structure of living organisms, which he made through the use of a microscope. He studied the anatomy of both plants and animals, and discovered tiny blood vessels in the lungs, which he called capillaries, and observed the structure of the lungs. He also studied the structure and function of various organs, including the brain and the liver, and his work helped to lay the foundations for the field of physiology.
Overall, these three scientists made significant contributions to the field of microscopy and their discoveries paved the way for modern-day microbiology and cell biology.
