Lise Meitner is an Physicst who researched radioactivity and nuclear physics. Born in Vienna, Austria Meitner studied physics and was the second woman to graduate with a PhD degree from the University of Vienna. In 1926, Lise Meitner became the first female physics professor at the University of Berlin where she started her research into nuclear physics. Lise Meitner started working on the new field of radioactivity with Otto Hahn. Together, they discovered a new radioactive element, Protactinium, in 1918. Later on in 1923, Meitner discovered the radiationless effect known as Auger effect, named after a french scientist who discovered the effect two years later. In 1938, Meitner was forced to flee from Austria to Copenhagen because of her Jewish roots. In Copenhagen, Hahn and Meitner met secretly to plan the next round of experiments. These new experiments provided the key evidence for their nuclear fission theory. In February of 1939, Meitner published the theory. In 1944, Hahn was awarded the Nobel Prize for Chemistry for his research into Nuclear Fission but Meitner was ignored. Later on, this mistake was partly rectified when Meitner and Hahn were awarded the Enrico Fermi Award. After her research was completed, Meitner retired to Cambridge, England in 1960 and sadly passed away later on that year on October 27th. Lise Meitner’s accomplishments changed the face of Nuclear Physics, Albert Einstein and many other agree that Lise Meitner is the most significant woman scientist of the 20th century. Recently in 1992, element 109, the heaviest known element in the universe was named Meitnerium (Mt) in her honor.
