She is best known as the inventor of the 'Apgar score, ' a method to summarise the birth of newborns.
The Google Doodle marks what would have been Apgar's 109th birthday. Countries across the world were quick to adopt the test and the Apgar Score is being used even today by obstetricians.
Born in 1909, Dr Virginia Apgar was the youngest of the three children.
As a medical student, Apgar noted that a number of babies that had seemed healthy at birth were dying soon after leaving the hospital.
The test is conducted in the first five minutes after birth, allowing doctors to determine which babies need immediate care.
Apgar invented the scoring system in 1952, and doctors have been using it for decades since.
Depending on the observed condition, each category is scored with 0, 1, or 2.
The Apgar Score's name is not just that of its creator - each letter refers to a part of the test. Score above 7 are normal and 4 to 6 are fairly low.
Dr. Apgar developed the test after noticing that, even though the general US infant mortality rate fell between the 1930s and 1950s, it remained constant for babies within the first day of life.
Apgar graduated from the College of Physicians and Surgeons at Columbia University in the United States with flying colours. She received a master's degree in public health from Johns Hopkins University in 1959, and was a director at the National Foundation for Infantile Paralysis, which is know known as the March of Dimes. She trained as a surgeon and specialised in anaesthesiology at a time when women were discouraged from practicing surgery.
But she could barely spend two years into her surgery residency as the then Chair of Surgery at the institution persuaded her to switch to anesthesia, an uncalled-for move that Columbia University termed "a reflection of the times".
The woman who came up with a scale to rate the health of newborn babies, Dr.
She trained in anaesthesia at the University of Wisconsin and Bellevue Hospital in the U.S., but returned to Columbia-Presbyterian Hospital in 1938. An anesthesiologist by training, she climbed the ranks at New York's Columbia-Presbyterian Hospital in the 1930s and '40s, when anesthesiology wasn't recognized as a medical specialty.
A USA postage stamp carrying her portrait was also released after her death.
