Stamen Gigov Grigorov (Bulgarian: Стамен Гигов Григоров; 27 October 1878 – 27 October 1945) was a very important Bulgarian physician and microbiologist. He is best known for discovering a special type of germ, called Lactobacillus bulgaricus. This germ is super important for making delicious yogurt. Grigorov also helped create an early treatment for tuberculosis, a serious lung disease.

A Life of Discovery
Early Life and Education
Stamen Grigorov was born on October 27, 1878, in a small village called Studen Izvor in Pernik Province, Bulgaria. The name "Studen Izvor" means "Cold Spring." He was a very bright student. He studied natural sciences in Montpellier, France. Later, he went to Geneva, Switzerland, to study medicine.
The Yogurt Secret
In 1905, when he was 27 years old, Grigorov made his most famous discovery. He was working in a lab in Geneva with Professor Léon Massol. There, he found a specific type of bacteria (a tiny living thing) that was responsible for making yogurt. This special bacteria was later named Lactobacillus bulgaricus by the scientific community. This name honors Bulgaria, where yogurt has been a traditional food for a very long time.
In the 1950s, a Bulgarian state-owned company created a special mix of these bacteria. This mix helped make what is known as "official Bulgarian yogurt." This unique blend is still sent to yogurt makers in many countries around the world today.
Fighting Tuberculosis
Grigorov's scientific work wasn't just about yogurt. In 1906, he also helped develop a treatment for tuberculosis. This was a very serious illness that affected many people. He worked with another scientist named Albert Calmette. They used a type of mold called Penicillium in their research.
Grigorov conducted many experiments. He tested the mold in laboratories (in-vitro, meaning in test tubes) and on lab animals (in-vivo, meaning in living beings). Later, he even tested it on human patients. His research showed that Penicillium fungi could help treat tuberculosis. This was a big step forward in medicine at the time.
Later Years
Stamen Grigorov continued his important work throughout his life. He passed away on October 27, 1945, on his 67th birthday.
Lasting Impact
A Glacier in His Name
To honor his contributions to science, a special place in Antarctica was named after him. The Grigorov Glacier is located on Brabant Island in the Palmer Archipelago. It's amazing to have a glacier named after you!
Honored by Google
More recently, on October 27, 2020, Stamen Grigorov was featured by Google. He was the subject of a Google Doodle for the day. This meant millions of people around the world learned about his important discoveries.
