Lise Meitner
1878-1968
Helping explain nuclear fission and opening new doors in science
Early Life
Lise Meitner was born in 1878 in Vienna, Austria. As a child, she loved learning and asking big questions about how the world works. At a time when many girls were not allowed to study science, Lise worked extra hard to follow her dreams.
She was especially curious about math and physics. With support from her family and a lot of determination, she became one of the first women in Austria to earn a doctorate in physics.
Becoming a Scientist
Lise moved to Germany to continue her studies and research. She worked with other scientists and spent long hours in laboratories, exploring the tiny particles that make up matter.
Even though she was very talented, Lise often faced unfair rules because she was a woman. She was not always paid or given proper credit, but she never gave up on science.
A Big Discovery
Lise Meitner helped explain a very important scientific idea called nuclear fission. This happens when a large atom splits into smaller parts and releases energy. Her work helped scientists understand how energy can come from atoms.
She developed this explanation with her nephew and fellow scientist, Otto Frisch, building on experiments done by her long-time research partner Otto Hahn. Together, their work changed the world of physics. Today, nuclear fission is used in science, medicine, and energy research.
Courage and Kindness
During a dangerous time in Europe, Lise had to leave Germany in 1938 to stay safe from the Nazi government. She moved to Sweden and continued her research there. Even when life was hard, she stayed focused on learning and helping others.
Lise believed science should be used to help people. She cared deeply about peace and responsibility in scientific work.
Legacy
Lise Meitner is remembered as a brave and brilliant scientist. An element on the periodic table, called meitnerium, was named in her honor.
Her story inspires young people everywhere to be curious, kind, and brave. Lise showed that with hard work and courage, you can make a difference in the world.
🎉 Fun Facts
Lise Meitner was the first woman to become a full professor of physics in Germany.
An element on the periodic table is named after her: meitnerium.
She loved long walks in nature to think about science problems.
Lise worked in science for over 50 years!
