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 microscop
