    Zacharias Janssen is associated with the invention of the Optical telescope in the year 1590
    1590 Zacharias discovered that when put a lens at the top and bottom of a tube and looked through it, objects on the other end became magnified therefore he invented the very first microscope called the Compound Microscope

  • Compound Microscope

    Compound Microscope
    1590- Zacharias Janssen is credited for the invention of the Compound Microscope by placing 2 lenses in a tube.
  • Period: to

    Miroscopes

  • Francesco Redi

    Francesco Redi
    1668 In one one of the first biological experiments, Francesco Redi was able to disprove the theory that maggots could be spontaneously generated from meat using a controlled experiment
  • Period: to

    Understanding Of Life

    1668- Redi created an experiment to generate maggots by placing meat into two different jars.
    1750 - Needham presented his theory of Spontaneous Generation (Life from Organic Matter) Challenged Redi's findings
