Who was Hans Christian Gram?
Hans Christian Gram was a Danish microbiologist whom Google is celebrating today on his 166th birthday.
The doodle that honours Gram on his birth anniversary today was illustrated by Danish guest artist Mikkel Sommer.
Gram was born in Copenhagen on September 13, 1853, and died in his home city on November 14, 1939, aged 86.
He was the son of Frederik Terkel Julius Gram, a professor of jurisprudence, and Louise Christiane Roulund.
The microbiologist studied at the University of Copenhagen and was an assistant in botany to the well-known Danish zoologist Japetus Steenstrup.
His study of plants introduced him to the fundamentals of pharmacology and the use of the microscope.
Gram then enrolled in medical school in 1878, before graduating in 1883.
He went travelling throughout Europe to study bacteriology and pharmacology between 1878 and 1885 after graduating.
In 1891, Gram taught pharmacology, and later that year was appointed professor at the University of Copenhagen.
In 1900, he resigned his chair in pharmacology to become professor of medicine.

What did he discover?
In Berlin, in 1884, Gram developed a method for distinguishing between two major classes of bacteria.
This technique, the Gram stain, continues to be a standard procedure in medical microbiology to this day.
His initial work involved the study of red blood cells in men.
Gram was among the first to recognise that macrocytes were characteristic of pernicious anaemia.
he was later appointed as a professor of medicine at the University of Copenhagen in 1900 after resigning from pharmacology.
During his career as a professor, he published four volumes of clinical lectures which became widely used in Denmark.
He retired from the University of Copenhagen in 1923.
