This technology, Gram Stein, continues to be standard practice in medical microbiology.

While treating the smear of bacteria with crystal violet stain, he discovered differences in the structure and biochemical performance of the samples, following iodine solution and organic solvent.

Gram’s results were published in a paper in 1884, from which the terms gram-positive and gram-negative were used.

Gram was a modest man, and in his early publication he commented, “I have published this method, although I know it is very defective and imperfect; we hope it will be in the hands of other researchers as well.”

Gram’s early work involved the study of red blood cells in men.

He was the first to recognize that Macrocyte were the hallmark of harmful anemia.

Gram was appointed Professor of Medicine at the University of Copenhagen in 1900.

As a professor, he has published four volumes of clinical lectures, which ae widely used in Denmark.

He retired from the University of Copenhagen in 1923 and died in 1938.
