John Tyndall (/ ˈ t ɪ n d əl /; 2 August 1820 – 4 December 1893) was an Irish physicist.His scientific fame arose in the 1850s from his study of diamagnetism.Later he made discoveries in the realms of infrared radiation and the physical properties of air, proving the connection between atmospheric CO 2 and what is now known as the greenhouse effect in 1859.
Tyndallization is a process from the nineteenth century for sterilizing substances, usually food, named after its inventor John Tyndall, that can be used to kill heat-resistant endospores. Although now considered dated, it is still occasionally used.

The investigations of the Irish physician John Tyndall, a correspondent of Pasteur and an admirer of his work, were decisive in disproving spontaneous generation. All the same, Tyndall encountered difficulties in dealing with microbial spores, which were not well understood in his day.
Third and finally, Louis Pasteur and John Tyndall experimentally disproved the (now superseded) theory of spontaneous generation, which suggested that life was constantly evolving from non-living matter and did not have a common ancestor, as suggested by Darwin's theory of evolution.
The Tyndall effect is light scattering by particles in a colloid such as a very fine suspension (a sol). Also known as Tyndall scattering , it is similar to Rayleigh scattering , in that the intensity of the scattered light is inversely proportional to the fourth power of the wavelength , so blue light is scattered much more strongly than red ...
