Lajos Jánossy (Budapest, 1912 March 2 – Budapest, 1978 March 2) was a Hungarian physicist, astrophysicist and mathematician and a member of the Hungarian Academy of Sciences. He carried out research in astrophysics, nuclear physics, quantum mechanics, mathematical physics and statistics, as well as electrodynamics and optics. == Biography == He was the adopted son of the philosopher György Lukács (1885–1971); brother of the economist and engineer Ferenc Jánossy (1914–1997); and father of Mihály Jánossy (1942–2004), András Jánossy (1944), István Jánossy (1945) (all three physicists), and Jánossy Anna, medical researcher. From the age of 6, he lived abroad: he attended university in Vienna and, later, in Berlin. For a few years, he worked with Kohlhörster in Berlin, and, then, with P.M.S. Blackett — who later became a Nobel Prize winner in 1948 — in the field of cosmic radiation at Birkbeck College in London and, later, at Manchester University. In 1947, he moved to Ireland and was appointed to a professorship at the Dublin Institute for Advanced Studies. He worked there as the leader of the Cosmic Radiation Laboratory for nearly three years. After the 1919 fall of the early Hungarian Soviet Republic, his mother and stepfather, Borstieber Gertrúddal and György Lukács, left the country together, and moved to Vienna where he attended secondary school. He was studied at the Vienna (1930–1934) and at the Humboldt University in Berlin. He worked in the laboratory of Werner Kolhörster in Berlin (1934–1936), in astrophysics . In 1936, fleeing Nazism, he moved to London, until 1938, carrying out research at Birkbeck College. From 1938 on he worked at the University of Manchester under the subsequent Nobel laureate Patrick Blackett on astrophysics, heading the cosmic radiation research group. In 1947 invited by Walter Heitler and Erwin Schrödinger he joined the Dublin Institute for Advanced Studies as a professor and group leader of the cosmic rays research laboratory. Invited by the Hungarian government, Jánossy returned home in 1950, not only for reasons of promised scientific possibilities, but also because his foster father and his mother had also returned there from their emigration in Moscow. Jánossy was charged with the task of managing the Cosmic Radiation Department at the Central Research Institute for Physics (Hungarian abbreviation: KFKI) founded in 1950. He was very active in scientific organisation, education and public life. He was appointed deputy director of the KFKI from 1950 to 1956, and the director from 1956 to 1970. In addition, he was also active in university education; the Department of Nuclear Physics at Loránd Eötvös University was established for him. He was the first head of the Department of Nuclear Physics from 1957 to 1970. His political engagement is attested by his membership, from 1962 until his death, in the Hungarian Socialist Workers 'Party, the Hungarian Socialist Workers' Party Central Committee. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Lajos Jánossy」の詳細全文を読む スポンサード リンク
