Robert Hooke was and English scientist born in 1635 and died in the year of 1703. Robert
Hooke was born in the town of Freshwater, which is located in the Isle of Write. Hooke was
born to a minister named John Hooke. Robert received a great deal of education that did
not take place in the classroom. He studied with the portraitist Sir Peter Lely (in his
youth). He was educated at the University of Oxford. Then after college he was an
assistant of Robert Boyle. He made curator of experiments to the royal society is 1662,
and secretary in 1677-88. Hooke is best known for his theory of elasticity, in
Hooke’s law. In 1665 Hooke became professor of Geometry at Gresham College, which
he occupied till his death. Despite being a famous scientist, there are no surviving
portraits of Hooke.

Hooke’s law of elasticity states that the amount an elastic body bends or stretches
out of shape (strain) is in direct proportion to the force (stress) acting on it. This
law applies as long as the body is still elastic. Increased stress beyond this limit will
change the shape of the body permanently. Robert Hooke had many accomplishments as a
scientists the law of elasticity is what he is most well know for.

Robert Hooke also was the first person to observe the cells of a plant. Using an early
microscope he observed the cells. Hooke took a cork layer of bark from an oak tree and
examined it with a microscope that he made. When observing the cells he noticed the
compartments looked like the small cells of a monastery, so he decided to call them cells.
This is a photo, one of hooke’s early observations. Hooke’s reputation as a
biologist is largely do to the book he wrote called Micrographia, which was published in
1665.

In the book Micrographia he started to use the word “cell” and described the
features of plant tissues that he was able to observe with his microscope. The word cell
gradually caught on with other scientist. Hooke said this about his early observations of
the plant cells, “I could exceedingly plainly perceive it to be all perforated and
porous, these pores or cells.” Robert Hooke had observed the first plant cell, and
cell wall.

Hooke's remarkable engineering abilities enabled him to invent and improve many mechanical
devices. Devices that he improved or invented included timepieces (for which he invented
the spiral spring), the quadrant, he constructed the first Gregorian telescope, and made
his own microscopes. Hooke had many ideas, but failed to follow through on most. He
