Mr Reg Whellock was headteacher at Greenshaw High School from 1965 – 1979
"It is with great sadness that we have to announce that Reg Whellock passed away on Friday, 4 September just short of his 101st birthday," said a spokesperson.
"He was guest of honour at our alumni event in July and spent a very enjoyable day catching up with staff, past and present, and former students and entertained everyone with his indefatigable memory and good humour."
