Albert Theuwissen was born in Maaseik (Belgium) on December 20, 1954. He received the degree in electrical engineering from the Catholic University of Leuven (Belgium) in 1977. His M.Sc. thesis work was based on the development of supporting hardware around a linear CCD image sensor. From 1977 to 1983, his work at the ESAT laboratory of the Catholic University of Leuven focused on semiconductor technology for linear CCD image sensors. He received the Ph.D. degree in electrical engineering in 1983. His dissertation was on the implementation of transparent conductive layers as gate material in the CCD technology.

In 1983, he joined the Micro Circuits Division of the Philips Research Laboratories in Eindhoven (the Netherlands) as a member of the scientific staff. Since that time he was involved in research of solid-state image sensing, which resulted in the project leadership of respectively SDTV- and HDTV imagers. In 1991 he became Department Head of the division Imaging Devices, including CCD as well as CMOS solid-state imaging activities.

He is author or coauthor of 200+ technical papers in the solid-state imaging field and issued several patents. He was co-editor of IEEE Micro special issue on Digital Imaging Nov./Dec. 1998 and of the IEEE Transactions on Electron Devices special issues on Solid-State Image Sensors, May 1991, October 1997 and January 2003. For the latest special issue IEEE-ED on image sensors, published in January 2016, he acted as the guest editor-in-chief. He was general chairman of the International Image Sensor Workshop in 1997, 2003, 2009 and 2015. He is member of the Steering Committee of the aforementioned workshop and founder of the Walter Kosonocky Award, which highlights the best paper in the field of solid-state image sensors. Together with his peers, Eric Fossum and Nobukazu Teranishi, he founded the International Image Sensor Society, a non-profit organization to stimulate sharing of technical knowledge in the field of digital image capturing.

In 1988, 1989, 1995 and 1996 he was a member of the International Electron Device Meeting paper selection committee. During several years he was a member of the technical committee of the European Solid-State Device Research Conference and of the European Solid-State Circuits Conference. From 1999 till 2010 he was a member of the technical committee of the International Solid-State Circuits Conference. For the same conference he acted as secretary, vice-chair and chair in the European ISSCC Committee and he was a member of the overall ISSCC Executive Committee. He acted as the Vice-Chair and Chair of the International Technical Program Committee respectively for the ISSCC2009 and ISSCC2010.

In 1995, he authored the book 'Solid-State Imaging with Charge-Coupled Devices'. This work is still considered as one of the main textbooks in the field of solid-state imaging. In 1998 he was nominated as an IEEE distinguished lecturer. This nomination was renewed in 2015. In 2000 he received the IEEE Fellowship.

In March 2001, he became part-time professor at the Delft University of Technology, the Netherlands. In Delft his main attention goes to the coaching of PhD students researching CMOS image sensors.

In April 2002, he joined DALSA Corp. to act first as the company's Chief Technology Officer and later as the Chief Scientist of DALSA Semiconductors. After he left DALSA in September 2007, he founded Harvest Imaging and since then he is fully focusing on training, coaching and consulting in the field of solid-state imaging technology.

In 2008 Albert Theuwissen received the SMPTE's (Society for Motion Pictures and Television Engineers) Fuji Gold Medal for his contributions in research, development and education in the field of solid-state image capturing. In 2010 he was elected to be the 'Electronic Imaging Scientist of the Year'. In 2013 he received the Exceptional Service Award of IISS and in 2014 the SEMI Award.
