John Kenneth Hulm
John Kenneth Hulm (4 July 1923, Southport, UK – 16 January 2004) was a British-American physicist and engineer, known for the development of superconducting materials with applications to high-field superconducting magnets. In 1953 with George F. Hardy he discovered the first A-15 superconducting alloy. John K. Hulm received his undergraduate degree in 1943 from the University of Cambridge and then worked on radar development until the end of WWII. After the war he returned to Cambridge and received his PhD in 1949 with a thesis on the thermal conductivity of superconductors. His thesis advisor was David Shoenberg. At the University of Chicago, Hulm was a postdoc from 1949 to 1951 and an assistant professor from 1951 to 1954. In 1954 he became employed at the Westinghouse Electric Corporation research laboratory in Pittsburgh. There he assembled and led a research team dealing with the physics of materials, especially superconductors. He was promoted in 1956 to manager of the ...

Bernd Matthias
Bernd T. Matthias (June 8, 1918 – October 27, 1980) was a German-born American physicist credited with discoveries of hundreds of elements and alloys with superconducting properties. He was said to have discovered more elements and compounds with superconducting properties than any other scientist. Education and career Bernd Theodor Matthias was born in Frankfurt, German Empire, Germany on June 8, 1918. He received his PhD in physics from the Federal Institute of Technology in Zurich in 1943.

Alumni Of The University Of Cambridge
Alumni (: alumnus () or alumna ()) are former students or graduates of a school, college, or university. The feminine plural alumnae is sometimes used for groups of women, and alums (: alum) or alumns (: alumn) as gender-neutral alternatives. The word comes from Latin, meaning nurslings, pupils or foster children, derived from "to nourish". The term is not synonymous with "graduates": people can be alumni without graduating, e.g. Burt Reynolds was an alumnus of Florida State University but did not graduate. The term is sometimes used to refer to former employees, former members of an organization, former contributors, or former inmates. Etymology The Latin noun means "foster son" or "pupil". It is derived from the Latin verb "to nourish". Separate, but from the same root, is the adjective "nourishing", found in the phrase '' alma mater'', a title for a person's home university. Usage in Roman law In Latin, is a legal term (Roman law) to describe a child placed in foster ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

John Eugene Kunzler
John Eugene Kunzler (April 25, 1923 – January 11, 2006) was an American physicist who conducted pioneering research into the field of superconducting magnets.Rogers, Madolyn Bowman"Superconducting magnets" ''Symmetry magazine'', December 1, 2008. Accessed March 30, 2023. "In 1954, G.B. Yntema at the University of Illinois and, in 1959, Stanley Autler at MIT, independently wound superconducting coils with cold-worked niobium and produced magnetic fields close to 10 kilogauss, an order of magnitude higher than before. The gauss race was on. The prize went to metallurgist John E. "Gene" Kunzler, whose group at Bell Labs produced 15 kilogauss using an alloy of molybdenum-rhenium. Kunzler filed for a patent (see image) on September 19, 1960, beating Autler's patent filing by 15 days. Kunzler's patent was issued first, on April 14, 1964."Khurana, Anil"Superconductivity Seen Above the Boiling Point of Nitrogen" ''Physics Today'', April 1987. Accessed March 30, 2023.

A15 Phases
The A15 phases (also known as β-W or Cr3Si structure types) are series of intermetallic compounds with the chemical formula ''A''3''B'' (where A is a transition metal and B can be any element) and a specific structure. The A15 phase is also one of the members in the Frank–Kasper phases family. Many of these compounds have superconductivity at around , which is comparatively high, and remain superconductive in magnetic fields of tens of teslas (hundreds of kilogauss). This kind of superconductivity ( Type-II superconductivity) is an important area of study as it has several practical applications. History The first time that A15 structure was observed was in 1931 when an electrolytically deposited layer of tungsten was examined. Discussion of whether the β-tungsten structure is an allotrope of tungsten or the structure of a tungsten suboxide was long-standing, but since the 1950s there has been many publications showing that the material is a true allotrope of tungsten.
