Robert Hooke

Definition

Robert Hooke was a 17th-century English scientist best known for his pioneering work in microscopy and for coining the term 'cell' in his book, 'Micrographia.' His observations of thin slices of cork led him to describe the microscopic structures he saw as 'cells,' which laid the foundation for cell theory and our understanding of the basic unit of life.
