Summary:
Google Doodle on Friday celebrates the 166th birthday of Danish microbiologist Hans Christian Gram who is known for his development of the Gram stain. The Google Doodle has been illustrated by Danish artist Mikkel Sommer, and it depicts Hans Christian Gram's work on the Gram strain, according to reports. Hans Christian Gram earned his MD from the University of Copenhagen in 1878 and then travelled through Europe to study bacteriology and pharmacology. He published his findings in a journal in 1884 which led to the coining of the terms 'Gram-positive' and 'Gram-negative'. The test, however, proved to be widely applicable and his staining method continues to be used even today, more than a century later..
