Jacek Furdyna

Jacek K. Furdyna was born on 6 September 1933 in Kamionka Strumilowa, Poland (now Kamianka-Buzka, Ukraine). After the Soviet invasion of Poland in 1939 he was deported to Siberia with his mother; his father was taken to the Gulag north of the Polar Circle. Following the German attack on the USSR, Polish deportees were formally amnestied. In 1942 he evacuated with his mother through Uzbekistan to Iran and began school in Tehran. The family path continued through Iraq (Baghdad and Kirkuk) into then-Palestine for further schooling. In 1947 he and his mother joined his father in the United Kingdom. At age fifteen he immigrated with his parents to the United States, settling in Chicago in 1948. He attended Holy Trinity High School in Chicago, operated by the Congregation of Holy Cross, where nearly all of his teachers were University of Notre Dame alumni.

Furdyna earned a Bachelor of Science degree in physics from Loyola University Chicago in 1955, graduating summa cum laude. He completed his Ph.D. at Northwestern University in 1960 under Sybrand Broersma. His doctoral thesis, published with Broersma as work on the microwave Faraday effect in silicon and germanium, launched a lifelong focus on electromagnetic phenomena in semiconductors. He then spent about two years as a postdoctoral fellow in Northwestern's Department of Electrical Engineering before moving to national laboratory and university posts.

From 1962 to 1966 Furdyna was on the staff of the M.I.T. Francis Bitter National Magnet Laboratory. He joined Purdue University's Physics Department as associate professor in 1966 and was promoted to professor in 1972. He served as a National Academy of Sciences Exchange Scholar at the Institute of Physics of the Polish Academy of Sciences and at Warsaw University (1972-1973), visited the National Research Council Canada in Ottawa (1981), and directed Purdue's NSF Materials Research Laboratory (1982-1985). In 1987 he moved to the University of Notre Dame as the Aurora and Thomas Marquez Chair of Information Theory and Computer Technology in the Department of Physics, a post he held until 2021 before becoming Professor Emeritus. At Notre Dame he co-directed work tied to materials fabrication and nanotechnology and ran an MBE laboratory that grew II-VI and magnetic semiconductor nanostructures for local and external collaborators. His publication list exceeded 900 papers spanning magnetoplasma effects, diluted magnetic semiconductors, blue-green laser structures, ferromagnetic DMS heterostructures, and Majorana-related nanowire experiments.

Furdyna married physicist Malgorzata (Margaret) Dobrowolska-Furdyna, whom he met in the condensed-matter community at Purdue after her postdoctoral work there. She returned from a faculty post in Poland to marry him, and both joined the University of Notre Dame faculty in 1987. They collaborated for decades on magneto-optics and diluted magnetic semiconductor quantum structures; Notre Dame photography from 2016 shows them together in the MBE lab in Nieuwland Hall. Public biographical sources emphasise his Polish wartime childhood, Chicago schooling under Holy Cross teachers, and lifelong academic ties between Poland and the American Midwest. Detailed public lists of children or other relatives beyond his spouse and the wartime account of his parents are not made public in the sources used for this profile.

Furdyna's public voice was primarily scientific. In reviews and invited papers he argued that combining semiconductor physics with magnetism opened a genuine new materials class, later called diluted magnetic or semimagnetic semiconductors, with consequences for magneto-optics, spin-dependent transport, and device heterostructures. His Notre Dame research descriptions stress molecular beam epitaxy as a route to quantum wells, quantum dots, and nanowires whose electronic and magnetic structure can be tuned for optical and spintronic applications. Collaborative work on GaMnAs-type ferromagnetic semiconductors focused on controlling the Fermi level and magnetic anisotropy as practical levers for spintronic memory and hybrid devices. He did not leave a widely cited corpus of political commentary; his documented commitments appear through research programmes, Polish-American scientific exchange, and fellowship in European-studies and physics societies.

Furdyna is widely cited as a central figure in diluted magnetic semiconductors. The 1988 Journal of Applied Physics review remains a landmark overview of DMS phenomena from giant Faraday effects to magnetic ordering. Structures grown in his Notre Dame MBE lab supported experiments at many institutions. The 2012 Nature Physics report with Rokhinson and Liu on the fractional a.c. Josephson effect in a semiconductor-superconductor nanowire entered the mainstream literature on Majorana signatures and topological superconductivity. Students, postdocs, and co-authors including Xinyu Liu, Margaret Dobrowolska, and international DMS groups carried the programme into ferromagnetic alloys, spin-orbit devices, and topological materials. Polish media after his death framed him as both a world-class materials physicist and a witness to twentieth-century deportation and exile, linking scientific renown to a personal history of displacement.

Furdyna was a Fellow of the American Physical Society, the American Association for the Advancement of Science, the Institute of Physics (United Kingdom), and the Nanovic Institute for European Studies at Notre Dame. The University of Warsaw awarded him a Doctor of Science honoris causa in 2002; Purdue University did the same in 2007. In 2009 the Polish Academy of Sciences awarded him the Nicholas Copernicus Medal, described by Notre Dame News as the Academy's highest honour, for contributions to novel semiconductor materials including magnetic semiconductors intended for advanced computing functions. Past Copernicus recipients include leading scientists across physics, chemistry, biology, mathematics, and engineering. He also held Notre Dame's Aurora and Thomas Marquez Chair of Information Theory and Computer Technology from 1987 to 2021.

Furdyna's name appears mainly in scientific and university media rather than general celebrity culture. He co-edited Diluted Magnetic (Semimagnetic) Semiconductors (1987, with R. L. Aggarwal and S. von Molnar), Diluted Magnetic Semiconductors (1988, with Jacek Kossut), and Chalcogenide: From 3D to 2D and beyond (2019, with X. Liu, S. Lee, T. Luo, and Y.-H. Zhang). Major review articles include the 1970 Reports on Progress in Physics survey with E. D. Palik on infrared and microwave magnetoplasma effects and the 1988 Journal of Applied Physics DMS review. Notre Dame News covered his Copernicus Medal in 2009. Gazeta Wyborcza's Ale Historia section published a Polish obituary on 29 September 2026 emphasising both his scientific pioneering and wartime biography. Conference talks and seminars on DMS and Majorana nanowires frequently cite or present the lines of work associated with his laboratory.

No major public controversies are documented in the biographical and news sources used for this profile. His scientific career unfolded in peer-reviewed condensed-matter physics, with priority and interpretation debates typical of competitive fields such as ferromagnetic semiconductors and Majorana signatures handled inside the literature rather than as personal scandal. This section records the absence of documented public controversy rather than an assertion that every scientific claim was undisputed.

Jacek K. Furdyna died on 28 September 2026 in the United States at the age of 93. Gazeta Wyborcza reported the death the following day, describing him as an outstanding physicist of world renown and a pioneer of research on magnetic semiconductors, nanostructures, and optical phenomena in semiconductors. Wikipedia's Deaths in September 2026 list records him under 28 September as a Polish-American physicist, citing that Polish coverage. Cause of death was not made public in the sources consulted. Tributes in Polish science and history media stressed his more than 900 publications, honorary doctorates, Copernicus Medal, and the wartime path from Siberia to Chicago that preceded his American academic career.
