Lise is a German-French short form of Elisabeth. Lise Meitner (1878-1968) was the Austrian-Swedish physicist who, in 1938, with her nephew Otto Frisch first interpreted Otto Hahn's experimental results as nuclear fission — coining the term. Hahn alone received the 1944 Nobel Prize in Chemistry for the discovery; Meitner's exclusion remains one of the most notorious oversights in Nobel history. *Element 109, Meitnerium, is named after her — and a 2008 movie Lise Meitner* dramatized her story.
Refused to work on the Manhattan Project, saying: "I will have nothing to do with a bomb."
Lise 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 Lise reduce to 9, The Giver. This is a traditional interpretive system, not a factual claim about the name.
