The image above shows a drawing of the microscope set up used by Robert Hooke in 1665 in which he first saw cells in a thin slice of cork. The first person to see living cells under a microscope was Anton van Leeuwenhoek. Robert Hooke was the first to In a 1665 publication called Micrographia, experimental scientist Robert Hooke coined the term cell for the box-like structures he observed when viewing cork tissue through a lens. Specifically, he observed that the lower plants all consist of one cell, while the higher ones are composed of (many) individual cells. In 1839 Theodor Schwann extended Schleidens cell theory to animals. One in biology education and one in educational leadership.

While your high school biology textbook may have identified him as the inventor of the instrument, Zacharias Jansen actually developed the first primitive microscope. No one else was able to see things as small as Leeuwenhoek. Antonie van Leeuwenhoek used single-lens microscopes, which he made, to make the first observations of bacteria and protozoa. This was an incredible feat as no one else was able to study these minuscule organisms until around 100 years later. Thus, Schleiden and Schwann became the first to formulate what was then an informal belief as a principle of biology equal in importance to the atomic theory of chemistry. He was the first to see microscopic foraminifera, which he described as little cockles.

WebWhat was Rudolph Virchow's contribution to the cell theory? His researches on lower animals refuted the doctrine of spontaneous generation, and his observations helped lay the foundations for the sciences of bacteriology and protozoology. Biologydictionary.net Editors. Discovery of bacteria Antonie Van Leeuwenhoek first observed bacteria in the year 1676, and called them animalcules (from Latin animalculum meaning tiny animal).
