Alfred Wilhelm Hübler (May 16, 1957 – January 27, 2018) was a German-born research physicist at the University of Illinois at Urbana-Champaign (UIUC) Frederick Seitz Materials Research Laboratory as well as a tenured faculty member in the University of Illinois Department of Physics. He was the director of the Center for Complex Systems Research (CCSR) and an external faculty member of the Santa Fe Institute.^[1]

Alfred Hübler was born in Munich, West Germany in 1957. He received his diploma in 1983 and Ph.D. in 1987, summa cum laude, from the Department of Physics, Technical University of Munich. His Ph.D. research was on controlling chaos and fractal particle agglomeration processes. After his Ph.D., Hubler joined Hermann Haken's synergetics group at the University of Stuttgart as a post doctoral researcher.

Hübler became a faculty member of the Department of Physics at the University of Illinois at Urbana-Champaign in 1989. He was also a long-time external faculty member of New Mexico's Santa Fe Institute. From 1993 to 1994, he was a Toshiba chair professor at Keio University in Tokio, Japan. He was Executive Editor of the journal Complexity.^[2]

Hübler published more than 50 papers in peer reviewed journals about his experimental and theoretical research on complex systems. His 2008 publication, entitled "A simple, low-cost data-logging pendulum built from a computer mouse" ^[3] is one of the most downloaded papers of all Institute of Physics journal articles (in the top 3%). The American Physical Society (APS) listed his paper on mixed reality on the APS tipsheet and invited him to give a press conference on this topic at the 2008 March meeting. Hübler has a 1997 US patent on minimum dissipation quantum-dot transistors and in 2009 the UIUC filed a patent in his name on digital quantum batteries.

Hübler died in 2018 from lymphoma.^[4]
