Robert Hooke

Definition

Robert Hooke was a 17th-century English scientist who is best known for his work in microscopy and for coining the term 'cell' in his book 'Micrographia'. His observations of cork under a microscope led him to describe the small, box-like structures he saw as cells, which laid the foundation for cell theory and significantly advanced our understanding of biological structures.

5 Must Know Facts For Your Next Test

1. Hooke's famous drawing of cork cells was published in 1665 in his book 'Micrographia', marking one of the first instances of cellular observation.
2. His work helped establish microscopy as a valuable scientific tool, allowing future scientists to explore the microscopic world.
3. Although Hooke was the first to use the term 'cell', he initially described them as resembling the small rooms, or cells, inhabited by monks.
4. Hooke's contributions extended beyond biology; he also made significant advances in physics, including Hooke's Law related to elasticity.
5. Despite his key role in cell biology, Hooke's relationship with other scientists, particularly Isaac Newton, was contentious and impacted his recognition in history.

Review Questions
