History and Foundations of Cell Theory

  • Historical Timeline:
    • 16651665 - Robert Hooke: First observed cellular structures and coined the term cell.
    • 18371837 - J.E.Purkyně (Jan Evangelista Purkyně): Established the fundamental groundwork for cell theory (Základ buněčné teorie).
    • 18391839 - Theodor Schwann and Matthias Schleiden: Formally formulated and authored the unified Cell Theory (Sepsali buněčnou teorii).

Evolutionary Classification and Origins of Cells
