I recently had the pleasure of reading the newest non-fiction book written by best-selling author MARISSA MOSS. THE WOMAN WHO SPLIT THE ATOM: THE LIFE OF LISE MEITNER is a detailed, and comprehensive account of an unknown female physicist who discovered nuclear fission but received little credit for her discovery.

Bestselling author-illustrator Marissa Moss tells the gripping story of Lise Meitner, the physicist who discovered nuclear fission. Here is the blurb:
As a female Jewish physicist in Berlin during the early 20th century, Lise Meitner had to fight for an education, a job, and equal treatment in her field, like having her name listed on her own research papers.
Meitner made groundbreaking strides in the study of radiation, but when Hitler came to power in Germany, she suddenly had to face not only sexism, but also life-threatening anti-Semitism as well. Nevertheless, she persevered and one day made a discovery that rocked the world: the splitting of the atom. While her male lab partner was awarded a Nobel Prize for the achievement, the committee refused to give her any credit.
Suddenly, the race to build the atomic bomb was on—although Meitner was horrified to be associated with such a weapon. “A physicist who never lost her humanity,” Meitner wanted only to figure out how the world works, and advocated for pacifism while others called for war.
The book includes an afterword, author’s note, timeline, select terms of physics, glossary of scientists mentioned, end notes, select bibliography, index, and Marissa Moss’s celebrated drawings throughout. The Woman Who Split the Atom is a fascinating look at Meitner’s fierce passion, integrity, and her lifelong struggle to have her contributions to physics recognized. Recommended for ages 9-up
I recently interviewed Marissa and asked her how this amazing story came about.
- How did you discover Lise Meitner and what led you to tell her story?
My youngest son is a grad student in physics and he told me about Lise Meitner. He knows how interested I am in people (often women) who deserve to be better known but haven’t gotten the credit they deserve. He warned me Meitner could be tricky since her discover led directly to the atomic bomb, but she herself refused to work on it (though she was asked) and the more I learned about her, the more compelling I found her.
2. How did you set up your research for such a complicated and technical project? What was the most difficult part?
I started by reading the two adult biographies written about her and followed up by going through her amazing archive of letters in documents, now in Cambridge, England where she spent the last years of her life. She not only had letters that were sent to her but copies of the letters she sent, so I could see both sides of the conversation. Most of the letters are in German, so I had to dust off my German language skills. It got easier the more letters I read as I became familiar with her writing style.
Two things were especially difficult — the first was to explain the physics involved clearly so a middle-grade student could understand it all. The second was not to sound too angry or outraged about Otto Hahn, her long-time partner who stole the credit for her discovery. I wanted to let the readers draw their own conclusions by simply describing what he said or did, but it was hard to keep calm whenever I wrote about him. Meitner herself was so generous and patient with him in all their many letters, even carefully explaining to him the momentous discovery which he didn’t understand at all, yet had no trouble taking full credit for.
3. What important ideas do you want readers to remember about Lise and her life’s work?
I want them to know that she was a scientist who faced incredible obstacles, first as a woman, then as a Jew, but she was determined to do what she loved. And she did it with absolute integrity, pure science for knowledge’s sake, never as a tool of politicians or the military.
4. Why this story and why now?
This was actually delayed due to covid (as so many things in publishing were). When I wrote most of it, Trump was president and the echoes of him and some of Hitler’s actions were positively eerie — the preference, for example, of relying not on experts for information, but on a trusted close circle. So when Hitler’s personal photographer dismissed the potential of atomic energy/weapons, Hitler agreed, rather than listening to the scientists in his government.
Now, with the Russian war on Ukraine, it seems even more timely, as the blanket German support of Hitler seems disturbingly parallel to the blanket Russian support of Putin. The German people thought Hitler was making their country stronger and that’s what mattered most. The average Russian seems to think the same of Putin.
5. What else should we know about the WOMAN WHO SPLIT THE ATOM?
Meitner’s integrity is an incredible example for all of us to follow. She always did what was right, not what was easy.
**STARRED REVIEW**
“Moss’ approach to this biography is notable in several ways, from the organization of facts into a very readable narrative to surprisingly clear explanations of Meitner’s scientific work and its significance. Even the back matter is uncommonly useful.”―Booklist
**STARRED REVIEW**
“A scorching profile of a brilliant physicist whose proper re cognition was long delayed thanks to sexism, antisemitism, and personal betrayal. . .A bright tale of a life dedicated to science, well stocked with dramatic moments and discoveries.” – Kirkus Reviews
