	The book “Microscopical Researches into the accordance in the structure and growth of animals and plants” by Theodor Schwann is the first scientific book where the “Cell therory” was published and considered as applicable to all living organisms. The book shown here corresponds to the first English edition, published in 1847, only a few years after the first german version. The book also contains accurate descriptions of animal tissues and plant tissues (the latter carried out by Schleiden).
	Impressed by the works from Leeuwenhoek, Robert Hooke decided to build microscopes and study live organisms and “inanimate bodies”. This genius of the XVII Century wrote the work “Micrographia”, which was published in 1665. The book itself is a collection of scientific papers corresponding to different observations. Observation XVIII, “Of the schematisme or texture of cork, and of cells and pores of some other such frothy bodies” is the first work where the word “cell” was used. Observing a microscopic cut of cork, Hooke deduced that the holes he saw corresponded to closed tridimensional structures rather than to pores, because corks do not let gas or liquid through. Then, the term was used to refer to this live units that form all living organisms: cells.
