Lise Meitner (1878-1968) was an Austrian physicist known for her work in radioactivity and nuclear fission.
Personal Life
Early Life
Lise Meitner was born in Vienna, Austria, on November 7, 1878, as the third of eight children. Her father was a lawyer from Moravia and strongly supported equal education for his sons and his daughters. Her mother's family had emigrated from Russia to Slovakia. Although they were Jews, the Meitners did not practice their religion, and most of the Meitner children converted to Catholicism. After showing early excellence in mathematics, Lise Meitner received private tutoring, and her passion for learning continued to grow.

In 1901, Meitner entered the University of Vienna, studying physics under Ludwig Boltzmann. After becoming the second woman to receive a PhD in Physics from the University of Vienna in 1906, she moved to Berlin to study with Max Planck, a physicist. For nearly seven years, Meitner worked as Planck's unpaid Physics Department assistant and published work on radioactive properties.

Scientific Contributions
Nuclear Fission
Meitner's experiments with Hahn provided evidence for nuclear fission and led to the creation of the atomic bomb.
In 1934, a scientist by the name of Enrico Fermi discovered that he could produce radioactive isotopes by neutron bombardment using uranium. This inspired Meitner and Hahn to continue experiments with uranium alongside their assistant, Fritz Strassman. After further tests on uranium, they believed they created radium as a product, but it was soon discovered to be barium. Confused by the results, Meitner and Strassman took a walk in the woods to clear their minds, and soon discovered that the nucleus of the uranium atom was splitting. Meitner and Hahn used Bohr's "liquid drop" model of the nucleus to explain and name the process "nuclear fission."
By the end of 1939, Meitner and Hahn's research had spread across America. In 1944, Albert Einstein used Meitner and Hahn's research to write a letter to President Franklin D. Roosevelt about the danger of atomic weapons. Meitner was recognized by President Harry Truman in 1945 at a dinner for the Women's Press Club and was also congratulated by Eleanor Roosevelt for being a strong woman in science. Meitner and Hahn's research was extremely important for the Manhattan project, in which the United States created an atomic bomb to drop on Japan and end World War II. Meitner became known as the "mother of the atomic bomb."
Other Information
Fun Facts
Three of Meitner's sisters went on to earn PhD degrees, most likely due to their father's strong support of equal education for men and women.
In 1918, Meitner discovered the element protactinium with Otto Hahn.
In 1992, element 109 was named Meitnerium in Lise Meitner's honor.
