John 'Jack' Gordon Clark (1926–1999) was a Harvard psychiatrist known for his research on the alleged damaging effects of cults.^[1]

He was the target of harassment from the Church of Scientology after he testified against it to the Vermont legislature in 1976.^[2]

The Psychiatric Times, when naming him 1991 psychiatrist of the year, described him as "a quiet, courageous man of conviction, who was fighting an all-too-lonely and unappreciated battle against well-financed, ruthless organizations."

   The Church of Scientology objected strongly to Clark's assertions, and the church and Clark battled in court. Clark said the church had engaged in a campaign of harassment against him. In 1988, he settled with the church and received an undisclosed amount of money, but agreed never to discuss the group publicly again.
