Who viewed cork under a microscope and saw cells?
Robert Hooke The first person to observe cells was Robert Hooke. Hooke was an English scientist. He used a compound microscope to look at thin slices of cork. Cork is found in some plants.
Who first observed cork cells?
Robert Hooke The cork was full of small empty compartments separated by thin walls. He called the compartments "pores, or cells." He estimated that every cubic inch of cork had about twelve hundred million of these cells. Robert Hooke had discovered the small-scale structure of cork.
What did Leeuwenhoek observe?
Leeuwenhoek is universally acknowledged as the father of microbiology. He discovered both protists and bacteria (1). More than being the first to see this unimagined world of 'animalcules', he was the first even to think of looking—certainly, the first with the power to see.
Who studied cork?
Hooke was one of the earliest scientists to study living things under a microscope. The microscopes of his day were not very strong, but Hooke was still able to make an important discovery. When he looked at a thin slice of cork under his microscope, he was surprised to see what looked like a honeycomb.
What did Robert Hooke do?
English physicist Robert Hooke is known for his discovery of the law of elasticity (Hooke's law), for his first use of the word cell in the sense of a basic unit of organisms (describing the microscopic cavities in cork), and for his studies of microscopic fossils, which made him an early proponent of a theory of …

What did Anton van Leeuwenhoek discover and when?
Discovery of microscopic life In 1674 he likely observed protozoa for the first time and several years later bacteria.
What did Theodor Schwann discover?
In 1848 Schwann accepted a professorship at the University of Liège, where he stayed for the remainder of his career. At Liège he investigated muscular contraction and nerve structure, discovering the striated muscle in the upper esophagus and the myelin sheath covering peripheral axons, now known as Schwann cells.
Who described cork cells?

What is Theodor Schwann most famous for?
Theodor Schwann, (born December 7, 1810, Neuss, Prussia (Germany)—died January 11, 1882, Cologne, Germany), German physiologist who founded modern histology by defining the cell as the basic unit of animal structure.
Who is Schleiden and Schwann?
Matthias Jacob Schleiden and Theodor Schwann were German scientists. Schleiden was a botanist, and Schwann was a physiologist. In 1835 both Schleiden and Schwann worked in the laboratory of zoologist Johannes Müller. The two became friends and eventually collaborated.
What did Leeuwenhoek examine?
Leeuwenhoek looked at animal and plant tissues, at mineral crystals and at fossils. He was the first to see microscopic foraminifera, which he described as "little cockles. . . no bigger than a coarse sand-grain." He discovered blood cells, and was the first to see living sperm cells of animals.

Theodor Schwann was an anatomist and physiologist who is best known for developing the cell doctrine that all living things are composed of cells. He established that the cell is the basic unit of all living things.
