Grange Hill actor Stuart Organ has died aged 72, his representative has confirmed. The British actor was best known for playing the firm but fair Peter Robson, the longest-serving member of staff in the school, on the children's television drama.
As Robson, he was a PE and geography teacher before being promoted to headteacher in the series about life in a London comprehensive school.
The show ran from 1978 to 2008 and made headlines for its gritty social realism, tackling issues such as racism, drug abuse, teenage pregnancy, mental illness and HIV and Aids.
Organ also portrayed Kevin Cross in the TV soap opera Brookside and featured in a host of shows including popular BBC sci-fi series Doctor Who, where he appeared alongside Sylvester McCoy.
