Robert Hooke FRS (/ h ʊ k /; 18 July 1635 – 3 March 1703) [4] [a] was an English polymath who was active as a physicist ("natural philosopher"), astronomer, geologist, meteorologist and architect. [5]
The cell was first discovered by Robert Hooke in 1665, which can be found to be described in his book Micrographia. In this book, he gave 60 observations in detail of various objects under a coarse, compound microscope. One observation was from very thin slices of bottle cork. Hooke discovered a multitude of tiny pores that he named "cells".
Since the invention of the microscope in the seventeenth century it has been known that plant and animal tissue is composed of cells : the cell was discovered by Robert Hooke. The plant cell wall was easily visible even with these early microscopes but no similar barrier was visible on animal cells, though it stood to reason that one must exist.

1665: Cell biology originated by Robert Hooke (1635–1703), who discovered the first cells in the course of describing the microscopic compartments within cork. [123] Early 19th century: the first recognition of what fossils were by Mary Anning.
In 1679, Robert Hooke wrote to Isaac Newton of his hypothesis concerning orbital motion, which partly depends on an inverse-square force. [94] [k] In 1684, both Hooke and Newton told Edmond Halley that they had proven the inverse-square law of planetary motion, in January and August, respectively. [96]
The double star nature of this system was discovered by Robert Hooke in 1664. [13] The two components have an angular separation of 7.606 arcseconds, [2] which can be resolved with a small telescope. The orbital period of the pair is greater than 5000 years. [14]
In 2007, Janice Neri, a professor of art history and visual culture, studied Hooke's artistic influences and processes with the help of some newly rediscovered notes and drawings that appear to show some of his work leading up to Micrographia. [5] She observes, "Hooke's use of the term "schema" to identify his plates indicates that he ...
