History
The method is named after its inventor, the Danish scientist Hans Christian Gram (1850–1938), who developed the technique while working with Carl Friedländer in the morgue of the city hospital in Berlin. Gram devised his technique not for the purpose of distinguishing one type of bacterium from another but to enable bacteria to be seen more readily in stained sections of lung tissue. He published his method in 1884, and included in his short report the observation that the Typhus bacillus did not retain the stain.

—Attributed to Georges Clemenceau (1841–1929)
“Whenever we read the obscene stories, the voluptuous debaucheries, the cruel and torturous executions, the unrelenting vindictiveness, with which more than half the Bible is filled, it would be more consistent that we called it the word of a demon than the Word of God. It is a history of wickedness that has served to corrupt and brutalize mankind.”
