Marie is the French form of Mary — from the Hebrew Miriam (uncertain; possibly "beloved" or "bitter"). Marie Skłodowska Curie (1867-1934) was the Polish-French physicist and chemist who discovered radium and polonium; coined the term "radioactivity"; and remains the only person to win Nobel Prizes in two different sciences (Physics 1903 with husband Pierre and Henri Becquerel; Chemistry 1911 alone).
Marie does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.
In Pythagorean numerology the letters of Marie reduce to 1, The Leader. This is a traditional interpretive system, not a factual claim about the name.
