Greetings, I am Otto Hahn. Born on March 8, 1879, my endeavors in radioactivity and radiochemistry have paved the way for groundbreaking discoveries in the realm of nuclear chemistry and nuclear fission. My collaboration with Lise Meitner led to the unearthing of radioactive isotopes of radium and the elucidation of nuclear fission in 1938, a pivotal moment in scientific history.
