Mr. Jones was born in Poughkeepsie, New York, and moved to San Jose in 1968. He attended Leland High School and UC Berkeley, where he graduated with a degree in chemistry.
Following graduation, he worked at the University of Erlangen in Germany. He returned to San Jose and began a career in the electronics industry. He later left the electronics industry to start his own company, SEJ Builders, building many beautiful homes on the Peninsula, say family members.
He is survived by his wife, Karyn; children Kathryn, Bradley and Michael; parents Pat and Bob Jones; and sister Lisa.
Memorials in his name may be made to the Stephen E. Jones Memorial Fund at Wells Fargo Bank, which has been set up for Kathryn Jones' college education.
