 David Bowie helped topple the Berlin wall.

The mother of modern physics, Marie Curie was known for her work with radioactive materials. This led to the discovery of elements like polonium and radium. Unfortunately, the research took a toll on her health, leading to her death from aplastic anemia.
The radioactive exposure also affected most of her belongings, including her clothes, furniture, and books. A century after her death, her notebooks have to be stored in a lead box, as they are still radioactive and will have to be so for another 1,500 years.
