MORE IDEAS FROM Heroes of Progress: Wilhelm Rontgen
On November 8, 1895, Wilhelm Röntgen was conducting experiments using a cathode ray tube. He noticed that when he used the cathode ray tube, a board on the other side of his lab that was covered in phosphorus began to glow. Even if he covered the tube's light in a thick black cardboard box, the phosphorous board continued to glow.
It became clear to Röntgen that he had discovered a new type of ray.
After many experiments, Wilhelm Röntgen found that many materials were transparent or translucent when interposed in the path of the rays. These materials included paper, wood, aluminum, and very importantly, skin and flesh.
A few weeks later, he took the first picture - a radiograph of his wife's hand. Röntgen published a paper on December 28, 1895, detailing his discovery titled “On a New Kind of Rays.” The news spread over the next two years. His discovery of the x-ray fundamentally changed medial practices forever.
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.
Louis Pasteur is known as the father of microbiology. He is renowned for developing the germ theory of disease, creating the process of pasteurization, and for changing the way scientists develop vaccines.
Lucy Wills was a hematologist who discovered that folic acid could be used to prevent life-threatening types of anemia in pregnant women.
Will's research into women's health during pregnancy has changed prenatal care and saved many lives. Today folic acid is recommended for all pregnant women.
She is the world's first successful suffragette. Her work and petitioning of New Zealand's parliament is the reason that the nation became the first country in the world to grant women the right to vote.
