The spelling of "Hans Christian Gram" can be a bit tricky to figure out for those unfamiliar with the Danish language. In IPA phonetic transcription, it is pronounced as "hæns ˈkʰʁestjæn ɡʁam".

Additionally, the silent "h" at the beginning of "Hans" can cause confusion for those not used to Danish orthography.
Hans Christian Gram was a Danish bacteriologist who lived from 1853 to 1938. He is known for his development of the Gram stain, a laboratory procedure used to differentiate and classify bacteria into two major groups: Gram-positive and Gram-negative.
The Gram stain is a fundamental technique in microbiology that involves four steps: applying a purple crystal violet stain, adding iodine to form a complex, washing with ethanol or acetone to decolorize, and finally counterstaining with safranin. This staining process enables the differentiation of bacterial species based on their cell wall compone
