The German scientist was the first person to identify electromagnetic radiation in a wavelength that we today know as an x-ray.
The most common usage of x-rays includes detecting broken or fractured bones, heart problems, breast cancer, scoliosis, and tumors. X-ray machines are used to help save the lives of millions of people.
He was born on December 27, 1827, to a poor Catholic family in Jura, France.
In 1842, he graduated with a degree in science from the Royal College of Besançon. A year later, he started studying at École Normale Supérieure, and in 1848, Pasteur was appointed professor of chemistry at the University of Strasbourg.

In 1928, Lucy Wills was recruited to India and tasked to investigate why millions of pregnant women in the developing world suffered from a severe and often deadly form of anemia.

But she noticed that richer women in India who had a more nutritious diet were less likely to become anemic during pregnancy.
