Robert Hooke

Definition

Robert Hooke was a 17th-century English scientist known for his pioneering work in microscopy and for coining the term 'cell' in his book, 'Micrographia.' His observations of thin slices of cork revealed tiny, hollow structures that he described as cells, which laid the groundwork for the development of cell theory and fundamentally changed our understanding of biology.
