Schwann's investigations were corroborated, in 1843, by Helmholtz.
Schwann then varied his experimental argument, with no alteration in the result.
When Schwann had laid the table and placed the dinner upon it, Cyprien took him aside.
Schwann's seeming inactivity has been a fruitful cause for conjecture.
The work was congenial, however, and Schwann remained here for five years.
The comparison of cells with crystals was made in 1838 by the founders of the cell-theory, Schleiden and Schwann.
As the title suggests, the main idea that actuated Schwann was to unify vegetable and animal tissues.
It was Schwann's merit to interpose between the tissue and the mere unorganised material a new element of structure, the cell.
The most marked feature of Schwann's career is the unfailing friendships that linked him to those with whom he was associated.
The relation between the unfertilised egg and the blastoderm which arises from it is not made altogether clear by Schwann.
Schwann (shvän), Theodor. 1810-1882.
German physiologist and pioneer histologist who described (1839) the cell as the basic structure of animal tissue. He isolated pepsin in 1836, and in 1838 he described the myelin sheath.
