Who was Peter Coshan?
Dr Coshan was a member of the teaching staff at Fettes College in Edinburgh, where former prime minister Tony Blair was once a pupil, from 1972 until his retirement in 2005.
The 75-year-old had taught biology and had also ran the school’s Duke of Edinburgh Awards scheme.
A petition on change.org has been started to call for Dr Coshan to be given recognition for the work he did on the Duke of Edinburgh scheme with a posthumous award.
In the petition, it says Dr Coshan was “warmly remembered by former pupils and staff as a leading figure at the school”
And it states it would be “befitting this wonderful educator some sort of posthumous award for his service and commitment to the Duke of Edinburgh’s Award scheme.”
Tributes have bee left on the petition page, with one calling him a “compassionate educator”, while another decribed him as a “brilliant teacher and a lovely man”.
Paying tribute to him Helen Harrison, head of Fettes College, previously said: “Peter was an inspirational biology teacher and he will be remembered fondly by many, not least by those who were taught by him, tutored by him and introduced to the hills through his enthusiasm for the Duke of Edinburgh Award Scheme, which he ran for 33 years.”
