How many scientists contributed to the creation of the microscope. What were each of their contributions?

11 Scientists

Explanation:

1. Hans and Zacharias Janssen (1590): They created the first compound microscope with more than one lens.

2. Robert Hooke (1667): He details the discoveries he made with the microscope in his book, 'Micrographia'.

3. Anton van Leeuwenhoek (1675): He discovered bacteria with the help of the microscope.

4. Joseph Jackson Lister (1830): He discovered that to get a clearer magnification, weak lenses ought to be used at different distances.

5. Ernst Abbe (1878): Formulated a mathematical theory that showed the relationship between resolution and the wavelength of light.

6. Richard Zsigmondy (1903): Discovered the ultra microscope that enabled the examination of specimen beyond light's wavelength.

7. Frit's Xernike (1932): invented the phase-contrast microscope.

8. Ernst Ruska (1938): He invented the electron microscope.

9. Gerd Binnig and Heinrich Rohrer(1981): Both discovered the scanning tunnel microscope.

his research revealed two genetically different groups of prokaryotes, which justified splitting kingdom monera into two kingdoms. the genetic and cellular differences were so great, that these two kingdoms were eventually placed into different domains in the current three-domain system.
