Jacobus Cornelis Haartsen (born 13 February 1963, The Hague, Netherlands) is a Dutch electrical engineer, researcher, inventor and entrepreneur best known for his role in producing the specification for Bluetooth.
He obtained his master of science degree in 1986 in electrical engineering (with honors). After a brief period at Siemens in The Hague and Philips in Eindhoven, he continued his studies and in 1990 obtained a PhD degree from TU Delft (also with honors) defending the thesis titled Programmable surface acoustic wave detection in silicon: design of programmable filters. Since 1991 he worked for Ericsson, first in USA between 1991 and 1993 and later, between 1993 and 1997, in Sweden. While working for Ericsson Mobile Terminal Division in Lund, he developed Bluetooth specification. Later, in 1997 he moved to Ericsson division in Emmen. Between 1997 and 2008 he was a part-time professor at University of Twente, teaching mobile radio communications systems. Currently, he's a wireless expert at Plantronics.
