Born and raised in Baltimore, Maryland, Michael Phelps began swimming at age seven at the urging of his mom. As a young boy, Michael was brimming with energy—more energy than most other kids his age—and Mrs. Phelps thought this sport could help keep him calm and focused. As Michael grew older, his skills improved, and he transformed into one of the greatest swimmers in the world, winning twenty-eight Olympic medals.

Born in Warsaw, Poland, on November 7, 1867, Marie Curie was forbidden to attend the male-only University of Warsaw, so she enrolled at the Sorbonne in Paris to study physics and mathematics. There she met a professor named Pierre Curie, and the two soon married, forming one of the most famous scientific partnerships in history. Together, they discovered two elements and won a Nobel Prize in 1903. (Later, Marie won another Nobel award for chemistry in 1911.)
