He is considered a pioneer of radioactivity and radiochemistry, and was also called the "founder of the atomic age" by his contemporaries and, officially, by the senate and the members of the Max Planck Society. In 1897, after taking his Abitur at the Klinger Oberrealschule in Frankfurt, Hahn began to study chemistry and mineralogy at the University of Marburg. His subsidiary subjects were physics and philosophy. Hahn joined the Students' Association of Natural Sciences and Medicine, a student fraternity and a forerunner of today's Nibelungia Fraternity. He spent his third and fourth semester studying under Adolf von Baeyer at the University of Munich. In 1901, Hahn received his doctorate in Marburg for a dissertation entitled On Bromine Derivates of Isoeugenol , a topic in classical organic chemistry. Hahn obtained a post as assistant in the Chemical Institute at Marburg, staying there two years, after which he worked under Sir William Ramsay at University College, London, from the autumn of 1904 to the following summer. His work here was rewarded by the discovery of a new radioactive substance, radiothorium, while working on the preparation of pure radium salts.

Credits Biography Childhood Otto Hahn was born on March 8, 1879, in Frankfurt am Main, the youngest son of the glazier and entrepreneur Heinrich Hahn (1845-1922) ("Glasbau Hahn") and his wife Charlotte Hahn, née Giese (1845-1905). Together with his brothers Karl, Heiner and Julius, he enjoyed a sheltered childhood. At the age of 15, he began to take a special interest in chemistry and carried out simple experiments in the laundry room. His father Heinrich, who became prosperous thanks to his hard work and thrift, and the originality of his ideas, would have liked Otto Hahn to study architecture, as he had built or acquired several residential and business properties. But his son Otto succeeded in persuading him that his ambition was to become an industrial chemist. Education In 1897, after taking his

Hahn, Otto Hahn, Otto (1879-1968), German physical chemist and Nobel laureate, best known for his contributions in the field of radioactivity. Hahn was born in Frankfort am Main and educated at the universities of Marburg and Munich. In 1911 he became a member of the Kaiser Wilhelm Institute for Physical Chemistry in Berlin. He served as director of the institute from 1928 to 1945, when it was taken into Allied custody after World War II. In 1918 he discovered, with Austrian physicist Lise Meitner , the element protactinium. Hahn, with his coworkers Meitner and German chemist Fritz Strassmann , continued the research started by Italian physicist Enrico Fermi: bombarding uranium with neutrons. Until 1939 scientists believed that elements with atomic numbers higher than 92 (known as transuranium elements) were formed when uranium was bombarded with neutrons. In 1938, however, Hahn and Strassmann , while searching for transuranium elements in a sample of uranium that had been irradiated with neutrons, found traces of the element barium. This discovery, announced in 1939, was irrefutable evidence, confirmed by calculations of the energies involved in the reaction, that the uranium had undergone fission, splitting into smaller fragments consisting of lighter elements. Hahn was awarded the 1944 Nobel Prize in chemistry for his work in nuclear fission. It was proposed in 1970 that the newly synthesized element number 105 be named hahnium in his honor , but another naming system was adopted for transuranium

Although his parents wanted him to become an architect, he eventually decided to study chemistry at the University of Marburg. There Hahn worked hard at chemistry, though he was inclined to absent himself from physics and mathematics lectures in favour of art and philosophy, and he obtained his doctorate in 1901. After a year of military service, he returned to the university as chemistry lecture assistant, hoping to find a post in industry later on. In 1904 he went to London, primarily to learn English, and worked at University College with Sir William Ramsay , who was interested in radioactivity. While working on a crude radium preparation that Ramsay had given to him to purify, Hahn showed that a new radioactive substance, which he called radiothorium, was present. Fired by this early success and encouraged by Ramsay, who thought highly of him, he decided to continue with research on

Otto Hahn B iography - Nobel Prize Winner (1944) Otto Hahn (8 March 1879 – 28 July 1968) was a German chemist. He received the 1944 Nobel Prize in Chemistry. He is considered a pioneer in the field of radioactivity. Hahn was born in Frankfurt am Main and studied chemistry in Marburg and Munich. After receiving his Ph.D. in 1901 he worked initially at Marburg University then, from 1904, at London, from 1905 at McGill University in Montreal under Ernest Rutherford and from 1906 in Berlin. of professor at the newly founded Kaiser-Wilhelm-Institute for Chemistry in Berlin in 1912. In 1918, he, together with Lise Meitner, discovered the first long-lived isotope of protactinium. When Meitner fled Nazi Germany in 1938, he continued work with Fritz Strassmann on elucidating the outcome of the bombardment of uranium with thermal neutrons. He communicated his results to Meitner who, in collaboration with her nephew Otto Robert Frisch, correctly interpreted them as evidence of nuclear fission (a phrase coined by Frisch). Thus Otto Hahn is credited as having been the first person to split the atom. Once the idea of fission had been accepted, Hahn continued his experiments and demonstrated the huge amounts of energy that neutron-induced fission could produce, either for energy production or warfare.
