Lise Meitner was a brilliant physicist who changed how we understand the tiny parts of our world.

She was born in Vienna, Austria, in November 1878. As a young girl, she was so curious about science that she kept a research notebook under her pillow.

She worked very hard to study physics at a time when it was difficult for women. By 1906, she became the second woman to earn a doctorate in physics from the University of Vienna. Her life was full of big discoveries and also many hard challenges. She eventually moved to Berlin to work with other famous scientists.

Meitner is most famous for helping to discover nuclear fission.

This discovery happened because of a special way atoms work. In 1938, chemists Otto Hahn and Fritz Strassmann hit uranium atoms with tiny particles called neutrons. They saw that the uranium turned into a different substance called barium. Meitner and her nephew, Otto Robert Frisch, looked closely at this data. They realized the uranium atom was actually splitting into smaller parts. They gave this splitting process the name "fission." This discovery showed that splitting an atom can release a huge amount of energy.

Meitner's scientific journey took her through many important places and eras.

She spent much of her career in Berlin at the Kaiser Wilhelm Institute for Chemistry. She was even the first woman to become a full professor of physics in Germany. However, life became very difficult due to the laws in Nazi Germany. Because she was Jewish, she lost her job in 1935. In 1938, she had to flee her home and move to the Netherlands. Later, she lived in Sweden for many years and eventually moved to Britain.

There are many important facts about her long and busy life.

She was born on November 7, 1878, into a family of eight children. Meitner worked with Otto Hahn for many years to find new radioactive elements. Together, they helped discover the element protactinium. Even though her work was vital, she did not receive the Nobel Prize in Chemistry in 1944. That prize went to her partner, Otto Hahn, instead. Still, she was nominated for the Nobel Prize many times between 1924 and 1967. Scientists even named element 109 "meitnerium" to honor her work.

We can see Meitner's legacy in the technology we use today. The discovery of fission led to the creation of nuclear reactors. It also led to the development of atomic bombs during World War II. Her work helps us understand the very building blocks of everything around us. Albert Einstein once called her the "German Marie Curie" because of her amazing talent.
