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.

Famous quotes containing the word history:
“All history attests that man has subjected woman to his will, used her as a means to promote his selfish gratification, to minister to his sensual pleasures, to be instrumental in promoting his comfort; but never has he desired to elevate her to that rank she was created to fill. He has done all he could to debase and enslave her mind; and now he looks triumphantly on the ruin he has wrought, and say, the being he has thus deeply injured is his inferior.”
—Sarah M. Grimke (1792–1873)
“The principle that human nature, in its psychological aspects, is nothing more than a product of history and given social relations removes all barriers to coercion and manipulation by the powerful.”
—Noam Chomsky (b. 1928)
“Literary works cannot be taken over like factories, or literary forms of expression like industrial methods. Realist writing, of which history offers many widely varying examples, is likewise conditioned by the question of how, when and for what class it is made use of.”
—Bertolt Brecht (1898–1956)
