Lise Meitner: The Woman Who Unlocked Nuclear Fission — Then Was Erased From History

Hinzugefügt: 2026-05-28

[00:00:00]A single photograph of a mushroom cloud over Bikini Atoll exists because one woman refused to stop calculating.

[00:00:09]Her name was Lise Meitner.

[00:00:12]Vienna, 1938.

[00:00:14]Theoretical physicist.

[00:00:16]She fled Nazi Germany with nothing but a winter coat and 10 marks in her pocket.

[00:00:22]From exile in Sweden, she received a letter from her lab partner, Otto Hahn, describing a strange experiment.

[00:00:30]Atom's splitting.

[00:00:32]He could not explain his own results.

[00:00:34]So, Meitner sat on a log in the snow with her nephew, did the math on scrap paper, and became the first person to explain nuclear fission.

[00:00:44]She literally named it.

[00:00:46]Hahn published the findings. He did not include her.

[00:00:50]The Nobel Committee awarded him the 1944 chemistry prize.

[00:00:55]Meitner was nominated 48 times across physics and chemistry. She never won.

[00:01:01]Here is what gets me. Every nuclear reactor on the planet, every conversation about atomic energy, every policy debate about weapons, all of it traces back to calculations she did while running for her life as a refugee.

[00:01:17]Element 109 carries her name.

[00:01:20]Meitnerium.

[00:01:22]A quiet footnote for the woman who unlocked the atom.
