The company was founded in 1971 with headquarters in Waltham, Massachusetts, and offices in Salt Lake City, Utah. It was acquired by Harman in 1993.
Lexicon traces its history to the 1969 founding of American Data Sciences by MIT professor Dr. Francis F. Lee and engineer Chuck Bagnaschi, developers of digital audio devices for medical heart monitoring.
