Dmitri Mendeleev vs Wilhelm Röntgen
Yes — based on their recorded years, Dmitri Mendeleev (1834–1907) and Wilhelm Röntgen (1845–1923) were alive at the same time for at least part of their lives.
Dmitri Mendeleev
Dmitri Mendeleev was a Russian chemist who formulated the periodic law and created an early version of the periodic table of elements, correctly predicting the existence of undiscovered elements.
Key achievements
- Formulated the periodic law and created the periodic table of elements in 1869.
- Successfully predicted the existence and properties of several then-undiscovered elements.
- Corrected the atomic weights of several known elements based on his periodic table framework.
- Became one of the most influential chemists in shaping the modern understanding of chemical elements.
Fast fact
Mendeleev's periodic table left deliberate gaps for undiscovered elements, and he successfully predicted the properties of elements like gallium and germanium years before they were actually discovered.
Full profile of Dmitri Mendeleev →Wilhelm Röntgen
Wilhelm Röntgen was a German physicist who discovered X-rays in 1895, a breakthrough that earned him the first-ever Nobel Prize in Physics and transformed medical diagnostics.
Key achievements
- Discovered X-rays in 1895 while experimenting with cathode ray tubes.
- Took the first-ever X-ray image, a photograph of his wife's hand.
- Became the first-ever recipient of the Nobel Prize in Physics in 1901.
- Declined to patent his discovery, allowing it to be used freely worldwide.
Fast fact
Röntgen refused to patent his discovery of X-rays, believing it should belong freely to the world for the benefit of humanity, forgoing what could have been enormous personal wealth.
