David Hillel Gelernter (born 1955) is a professor of computer science at Yale University. In the 1980s, he made seminal contributions to the field of parallel computation, specifically the tuple space coordination model, as embodied by the Linda programming system. Bill Joy attributes Linda as the inspiration for many elements of JavaSpaces and Jini.
In 1993, Gelernter was critically injured opening a mailbomb sent by Theodore Kaczynski, who at that time was an unidentified but violent opponent of technology, dubbed by the press as "the Unabomber". He recovered from his injuries but his right hand and eye were permanently damaged. He chronicled the ordeal in his 1997 book Drawing Life: Surviving the Unabomber.
He helped found the company Mirror Worlds Technologies, which created software using ideas from his book, Mirror Worlds: or the Day Software Puts the Universe in a Shoebox...How It Will Happen and What It Will Mean (1992). Gelernter believed that computers can free users from being filing clerks by organizing their data. The company saw few sales, and disbanded in late 2003.
In 2003, he was nominated to and became a member of the National Council on the Arts.
In 2006, Gelernter joined the scientific advisory board of theLifeboat Foundation.
Gelernter contributes to magazines such as City Journal, The Weekly Standard, and Commentary which are generally considered neoconservative. For seven months, he contributed a weekly op-ed column to the LA Times.
