Hans Christian Gram published his discovery in a journal in 1884 under the names Gram-positive and Gram-negative. Also told that the Gram-Positive Bacteria Microscope showed purple color, because the layer of the cell was very thick due to which it could not dissolve. At the same time, the cells of Gram-Negative Bacteria were very thin, due to which they dissolved.

Hans Christian Gram received a Doctor of Medicine degree from Copenhagen University in the year 1878. After this, he went to Europe to study bacteriology and pharmacology. While working at the Microbiojilt Lab in Berlin, he notices that mixing of bacteria spots into crystal violet stains (iodine solution and organic solvent) gives different structure and biochemical function in different samples.

Hans Christian Gramm wrote in the journal, "I am publishing this method, although I know it is incomplete now and has many faults, but I hope that an explorer will read this journal and further develop this method." Will be successful in increasing. "
Danish scientist Hans Christian (Danish Microbiologist) died in 1938 at the age of 85. Gram staining technique has been used in the history of microbiology even after his death and is still being used today. This technique invented by him is still used in the Biology Student Lab.
