Biography
Wilhelm Conrad Röntgen was born on March 27, 1845, in Lennep, Prussia (now part of Remscheid, Germany), to Friedrich Conrad Röntgen, a textile merchant, and Charlotte Constanze Frowein. When he was three, his family moved to the Netherlands, where he spent most of his childhood and youth. Despite academic setbacks due to a disciplinary incident at Utrecht Technical School, Röntgen pushed through and got into ETH Zurich in 1865 to study mechanical engineering.
After finishing his degree at ETH Zurich in 1868, Röntgen earned his doctorate in 1869 from the University of Zurich under August Kundt. He followed Kundt to the University of Strasbourg in 1872, working as an assistant and later becoming a lecturer. His academic career included roles at several German universities like the University of Hohenheim, the University of Giessen, and the University of Würzburg, where he became a professor of physics in 1888.
On November 8, 1895, while experimenting with a cathode ray tube at the University of Würzburg, Röntgen made the groundbreaking discovery of X-rays. He noticed a fluorescent screen glowing in his lab while the cathode ray tube was active, even though it was shielded from direct light. He found these mysterious rays could pass through different materials and create images of internal structures, like human bones. Röntgen studied these rays, initially calling them "X-rays" because their nature was unknown.
Röntgen's discovery changed medical diagnosis and scientific research. He published his findings in December 1895, and the medical applications were quickly recognized. In 1900, he took a position at Ludwig-Maximilians-Universität München, where he continued his research until retiring in 1920. In 1872, he married Bertha Ludwig, and they adopted her niece, Josephine Bertha Ludwig. Röntgen received many honors for his work, including being the first Nobel Prize in Physics winner in 1901. He died on February 10, 1923, in Munich, leaving behind a scientific legacy that transformed medical practice and physics.
Before Fame
Röntgen's journey to becoming a renowned scientist wasn't straightforward. After being expelled from Utrecht Technical School for not giving up the name of a classmate who had drawn a teacher's caricature, he sought different ways to pursue higher education. His enrollment at ETH Zurich marked the start of his serious scientific career, where he built a strong base in mathematics and physics.
The late 19th century saw a lot of scientific breakthroughs, especially in physics and chemistry. New electrical devices and vacuum tubes opened up fresh experimental opportunities. Röntgen's mentor, August Kundt, taught him careful experimental methods and precise measurement techniques, which were crucial for his later revolutionary work with electromagnetic radiation.

Did You Know?
- 01.Röntgen refused to patent his X-ray discovery, believing that scientific discoveries should benefit all humanity freely
- 02.The first X-ray image he took was of his wife Bertha's hand, showing her wedding ring and bones, which reportedly frightened her
- 03.He destroyed most of his laboratory notes and correspondence before his death, making it difficult for historians to trace the exact details of his discovery process
- 04.The element roentgenium (atomic number 111) was named in his honor in 2004
- 05.Despite his fame, Röntgen was known for his modest lifestyle and avoided public speaking about his discoveries
