   Dutrochet is also considered to be the founder of the cell theory; but his ideas are actually more in the nature of shrewd, intuitive anticipations rather than conclusions based on his own microscopic observations. His illustrations are not convincing and it seems that, at least in some cases, Dutrochet’s “globules” (cells) were optical ...
