Lise Meitner (1878-1968) was born in Vienna, the daughter of the first Jewish lawyer in Austria. Meitner showed an early interest in nuclear physics, working alongside such greats as Max Planck and Neils Bohr. Following World War I (in which she served as an x-ray nurse), Meitner discovered the famous “Auger effect”, but all the recognition was taken from her and given to Pierre Auger, hence the name. Soon after, she became the first-ever female professor of physics in Germany, but it did not last. Meitner was forced to flee from the Nazis. Over the course of her career, she helped discover many new elements of the periodic table, but by far her greatest achievement was the discovery of nuclear fission. Meitner was the first to show a nuclear chain reaction can release tremendous amounts of energy, the basis for nuclear bombs (and power plants). This inspired celebrity genius Albert Einstein to write a letter to President Roosevelt, initiating the Manhattan Project. Meitner was asked to work on the Project, but she refused with the words: “I will have nothing to do with a bomb!” Nonetheless, she is often called the Mother of the Atomic Bomb. Unbelievably, she was slighted once again when the Nobel prize for nuclear fission was given to Otto Hahn. If it is any consolation, the element Meitnerium (Mt, number 109) is named after her. November 17 was her birthday.

Rosalind Franklin (1920-1958) The world’s most famous biophysicist was born into a wealthy Jewish-British family, well-known for their roles in founding the Jewish state and helping Jews flee from the Nazis. Her great-uncle, Herbert Samuel, was the first observant Jew in history to serve in the British government, and carried the title “Viscount”. From an early age, Franklin was noted for her talent in scientific exploration. Combining her knowledge of biology, chemistry and physics, she was able to produce the highest quality images of DNA and RNA, evidence used by Watson and Crick to deduce DNA’s structure, a breakthrough moment for science. Additionally, she discovered DNA’s two forms (A and B), designed an ingenious method to separate them, and unraveled the mysteries of TM virus. Likely due to high doses of radiation, Franklin battled at least three different types of cancers. But this wouldn’t slow her down. She continued working, publishing 13 papers and serving on the team that developed the vaccine for polio. Unfortunately, she succumbed to her illnesses at a very early age, and was unable to claim her Nobel prize (which is not awarded posthumously). She would become an icon of feminism, breaking the barriers of the then male-dominated world of science. Franklin’s work has been described as “the most beautiful x-ray photographs of any substance ever taken”.
