Griffith's experiment discovering the "transforming principle" in Streptococcus pneumoniae (pneumococcal) bacteria. Griffith's experiment, [1] performed by Frederick Griffith and reported in 1928, [2] was the first experiment suggesting that bacteria are capable of transferring genetic information through a process known as transformation.
Frederick Griffith (1877–1941) was a British bacteriologist whose focus was the epidemiology and pathology of bacterial pneumonia.In January 1928 he reported what is now known as Griffith's experiment, the first widely accepted demonstrations of bacterial transformation, whereby a bacterium distinctly changes its form and function.

Fred (Friedrich) Neufeld (17 February 1869 – 18 April 1945) was a physician and bacteriologist who discovered the pneumococcal types. This discovery led Fred Griffith to show that one pneumococcal type could be transformed into another (Griffith's experiment).
This broad concept is now known as the genetic code. It was Crick, along with J.S. Griffith and Leslie Orgel (member of the RNA Tie Club), describing the 20-amino acid prediction as the "magic number," introduced the proper concept in 1957: [The] order of the amino acids is determined by the order of the nucleotides of the nucleic acid.
Invisible Agent (1942): Jon Hall stars as Frank Griffin Jr. / Frank Raymond / Invisible Man. Raymond is the nephew of the original Invisible Man Jack Griffin and Frank Griffin's son, but he heroically uses the formula on himself to help the Allies during WWII after the Pearl Harbor Attack and after a bunch of Axis Powers spies led by Conrad ...

Alan Arnold Griffith CBE FRS [1] (13 June 1893 – 13 October 1963), was an English engineer and the son of Victorian science fiction writer George Griffith.Among many other contributions, he is best known for his work on stress and fracture in metals that is now known as metal fatigue, as well as being one of the first to develop a strong theoretical basis for the jet engine.
