Aug 25, 2009 · Fawcett, elected as the first president of the newly formed American Society for Cell Biology in 1961, described the early days of electron microscopy as “filled with the same excitement and anticipation of discovery that attends the opening up of a new continent for geographic exploration.

Don Wayne Fawcett (March 14, 1917 - May 7, 2009) was a pioneer of electron microscopy and one of its greatest practitioners for studying the organization of cells and tissues. His greatest achievement was his description of the structure of spermatozoa and the male reproductive system.

Aug 25, 2009 · Cell biology owes some of its greatest discoveries to the electron microscope, and few were more passionate about its power to “wrest from nature her closely guarded secrets” than Don Wayne Fawcett.

Before we get started on the history of cell biology, let’s have a quick refresher on the basic structure of individual cells. Cells come in various types, from prokaryotic cells, such as bacteria and archaea, to eukaryotic plant and animal cells. Within these groups, there are further distinct cell types, such as red blood cells, neurons, and epit...
The cell theory, or cell doctrine, states that all organisms are composed of similar basic units of organization called cells. The concept was formally articulated in 1839 by Schleiden & Schwann and has remained as the foundation of modern biology. The idea predates other great paradigms of biology, including Darwin’s theory of evolution (1859), Me...
While the invention of the telescope made the Cosmos accessible to human observation, the light microscope opened up smaller worlds, showing what living forms were composed of. The cell was first discovered and named by Robert Hooke in 1665. He remarked that it looked strangely similar to cellula or small rooms which monks inhabited, thus deriving ...
In 1838, Theodor Schwann and Matthias Jakob Schleiden were enjoying after-dinner coffee and talking about their studies on cells. It has been suggested that when Schwann heard Matthias Schleiden describe plant cells with nuclei, he was struck by the similarity of these plant cells to animal cells he had observed in tissues. The two scientists went ...
All known living things are made up of cells.The cell is the structural & functional unit of all living things.All cells come from pre-existing cells by division. (Spontaneous Generation does not occur).Cells contain hereditary information, which is passed from cell to cell during cell division.Below is a timeline of some of the key events in the development of cell theory and cell biology. 1595 – Jansen is credited with the first compound microscope. 1655 – Hooke described ‘cells’ in cork. 1674 – Leeuwenhoek discovered protozoa. He saw bacteria some nine years later. 1833 – Brown described the cell nucleus in cells of the orchid. 1838 – ...
In the history of cell biology, there have been many individual scientific discoveries and technological developments, from the invention of the microscope, allowing us to see individual cells, to the discovery of fluorescent proteins and the invention of powerful electron microscopes, allowing us to study the function and structure of cells in gre...

Cells are divided into two main classes, initially defined by whether they contain a nucleus. Prokaryotic cells (bacteria) lack a nuclear envelope; eukaryotic cells have a nucleus in which the genetic material is separated from the cytoplasm.
