Microscopic cells were first discovered and named by the English scientist Robert Hooke in 1665, when he observed thin slices of cork under a microscope and saw tiny boxlike compartments he called ā€œcells.ā€

Quick Scoop

  • In 1665, Robert Hooke used a compound microscope he designed to study very thin slices of cork.
  • He noticed a pattern of many tiny compartments that reminded him of small rooms in a monastery, so he called them ā€œcells,ā€ introducing the term into science.
  • A few years later, Antonie van Leeuwenhoek went further and observed living single‑celled organisms (ā€œanimalculesā€), but the credit for discovering and naming microscopic cells goes to Hooke.
