Dr. Bruce P. Strauss, a longtime pillar of applied superconductivity and a lifelong servant of its global community, passed away on January 4, 2026.

Bruce was born in 1942 in Elizabeth, New Jersey, to Edward and Solea Strauss. From an early age, he displayed a strong interest and exceptional aptitude in technology. While still in high school, he earned his amateur radio license (call sign K2SZO), reflecting an enduring passion for electronics and communication technologies.

He received his S.B. degree in 1964 and his Sc.D. (Ph.D.) in Materials Science in 1967 from the Massachusetts Institute of Technology. During his doctoral work under Professor Robert Rose, Bruce achieved a landmark result: the fabrication of the first million-filament superconducting composite through repeated extrusion of Cu–Nb conductors. This early accomplishment foreshadowed a career defined by both technical innovation and practical impact. He later earned an MBA from the University of Chicago in 1972 while working at Fermilab, combining scientific excellence with strategic and managerial insight.

Following brief appointments at Avco Everett Research Laboratory and Argonne National Laboratory, Bruce joined Fermi National Accelerator Laboratory in 1969, where he entered a period of exceptional productivity and influence. He helped build the original 200 GeV proton accelerator ring that still serves as the main injector ring for the Fermilab proton accelerator complex. At Fermilab, he played a central role in the development of
superconducting accelerator magnet technology, particularly the use of multifilamentary NbTi conductors. His leadership helped catalyze the emergence of a global superconducting wire and cable industry. Under Bruce’s guidance, key innovations became foundational technologies for high-energy physics accelerators worldwide.

Bruce sent Bob Remsbottom on the road for approximately five years to help establish a production line for the Rutherford cable used in the Tevatron magnets. Every accelerator magnet built since the Tevatron has used NbTi wire and Rutherford cable technology that Bruce helped pioneer. These advances culminated in the Tevatron, the world’s first large-scale superconducting particle accelerator, which operated from 1983 to 2011 as the highest-energy accelerator of its time. The technologies Bruce helped develop at Fermilab remain the basis for virtually all subsequent superconducting accelerator magnets, including those used in today’s most advanced facilities.

Following his successes in superconducting magnet development at Fermilab, Bruce transitioned to industry, having been recruited by John Steckly to the startup Magnetic Corporation of America. There, he contributed to the commercialization of superconducting magnet systems for magnetic resonance imaging (MRI), helping translate accelerator technologies into transformative medical applications.

From 1984 onward, Bruce served as an independent consultant to numerous government agencies, most notably the U.S. Department of Energy (DOE). He later joined the DOE Office of High Energy Physics, first as an Intergovernmental Personnel Act (IPA) appointee and subsequently as a federal program manager. Between 1997 and his retirement in 2019, he oversaw critical programs in high-field superconducting materials, advanced accelerator magnets, and U.S. contributions to the Large Hadron Collider (LHC). His stewardship helped sustain U.S. leadership in superconducting technology and ensured successful collaboration on one of the most ambitious scientific instruments ever built.

Even after retirement, Bruce remained in high demand as a consultant, continuing to advise major high-energy physics initiatives with his characteristic insight and pragmatism.

Beyond his technical achievements, Bruce’s legacy is inseparable from his extraordinary service to the superconductivity community. He attended the first Applied Superconductivity Conference (ASC) in 1966 and became its Treasurer in 1974—a role he fulfilled with unwavering dedication for more than 50 years. His stewardship was instrumental in establishing ASC as a financially stable and globally respected conference series. Bruce was a co-organizer of the 1974 ASC, where he and David Larbalestier first met. David recalls being invited to Fermilab after the conference and being struck by the sight of a “graveyard” of 20 or 30 dipole magnets that he, Dave Sutter, and many others had been building in the prior two years. Bruce attended every biennial ASC conference except one (2022, due to illness), including the 2024 meeting in Salt Lake City, Utah.

Bruce also served the IEEE Council on Superconductivity (IEEE-CSC) in multiple leadership roles, including Treasurer and President. During his tenure, he strengthened the Council’s financial foundation and expanded its educational and outreach activities, including support for the Applied Superconductivity Educational Foundation. He was deeply committed to mentoring the next generation, frequently advising students and young professionals on navigating scientific careers beyond the classroom. He especially valued participating in panels advising students about “what they don’t teach you in school.” His influence on individuals—and through them, on the field—was profound and far-reaching.

Bruce coached and recruited brilliant young engineers. How many careers did he shape? How many scientists found their path because he recognized their potential and took the time to nurture it? We may never know the full count, but it is undoubtedly substantial.

In recognition of his sustained and transformative contributions, Bruce was elevated to IEEE Fellow in 2005, with the citation “For leadership in low temperature superconducting materials and magnet systems.” He received the IEEE Council on Superconductivity’s Max Swerdlow Award for Sustained Service to the Applied Superconductivity Community in 2012. These honors are bestowed on only a very small fraction of the community,
acknowledging sustained, transformative service, with exceptional and lasting impact on the field.

Bruce’s professional life was marked not only by technical excellence, but also by generosity, mentorship, and a deep commitment to community. He had a remarkable ability to recognize potential in others and guide them toward meaningful careers. The number of scientists and engineers whose paths he shaped is immeasurable, but unquestionably large.

An oral history of Bruce’s life and career, recorded by the IEEE History Center in 2016, captures both his technical contributions and his personal reflections:
