from 1949 until 1974, american-born leonard jan le vann was the medical superintendent of the provincial training school (pts). upon arriving at the school, le vann took on positions both in surgery and psychiatry, which enabled him to assess students as well as perform operations when necessary. past pts staff recalled his meticulous attention to detail, especially in delegating their tasks. le vann ordered nurses to maintain extensive reports on everything from children's bowel movements to their sexual interests. he also commanded a very strict work environment in which no personnel spoke to their supervisors, unless spoken to. during the 1960s, le vann "ran the institution almost...like a gestapo," a former pts psychologist remembers. it was later revealed that le vann had kept several significant secrets. in 1995, 8 years after his death, it was found that the medical director never actually obtained accreditation to practice psychiatry. his first wife also discovered that, in order to disguise his jewish descent, the man had undergone a name-change at a young age.
