A. (Albert) Calmette

Born in Nice in 1863, Albert Calmette became a French physician, bacteriologist, and immunologist whose work was closely tied to the Pasteur movement. After training in medicine, he joined the wider network of scientists inspired by Louis Pasteur and went on to found the first overseas Pasteur Institute in Saigon, where he worked on infectious disease, public health, and laboratory medicine.

Calmette is most famous for his long collaboration with veterinarian Camille Guérin, which led to the development of Bacillus Calmette-Guérin, or BCG, the tuberculosis vaccine that carries their names. He was also known for work on tuberculosis diagnosis and prevention, and for developing an early antivenom for snake bites, showing how widely his research reached across urgent medical problems of his time.

Later, at the Pasteur Institute in Lille and in broader public health work, he promoted practical measures to fight disease among ordinary people, including anti-tuberculosis efforts aimed at prevention as well as treatment. He died in Paris in 1933, but his name remains part of everyday medical history through BCG and his lasting influence on bacteriology and preventive medicine.
