Theodor Schwann (German pronunciation: [ˈteːodoːɐ̯ ˈʃvan]; [1] [2] 7 December 1810 – 11 January 1882) was a German physician and physiologist. [3] His most significant contribution to biology is considered to be the extension of cell theory to animals.
From these conclusions about plants and animals, two of the three tenets of cell theory were postulated. 1. All living organisms are composed of one or more cells 2. The cell is the most basic unit of life. Schleiden's theory of free cell formation through crystallization was refuted in the 1850s by Robert Remak, Rudolf Virchow, and Albert ...

Robert Remak (26 July 1815 – 29 August 1865) was an embryologist, physiologist and neurologist, born in Posen, Prussia, who discovered that the origin of cells was by the division of pre-existing cells. [1] as well as several other key discoveries.
The German-Polish physician Robert Remak suspected that he had already discovered animal cell division in the blood of chicken embryos in 1841, [56] but it was not until 1852 that he was able to confirm animal cell division for the first time in bird embryos, frog larvae and mammals. [57]

He also recognized the importance of the cell nucleus, discovered in 1831 by the Scottish botanist Robert Brown, [6] and sensed its connection with cell division. In 1838, the two scientists M. J. Schleiden and Theodore Schwann formulated a theory about cellular structure which stated, 'All the living organisms are made up of cells and the cell ...
