Danish bacteriologist Hans Christian Gram developed the Gram staining method. This staining technique helps to differentiate the bacteria of the two larger groups: gram-positive and gram-negative bacteria. In this technique, primary stains (methylene blue or crystal violet) and secondary stain (safranin) are used for the differentiation of bacteria based on the color retaining ability of the bacterial cells.
