Around 80 mourners paid their last respects to Malcolm Cottam - the cyclist killed in a collision on the Dronfield bypass, and who went unidentified afterwards for a week.
Mr Cottam was a former teacher at The City School. A funeral for the 55-year-old was held yesterday at Barnsley Crematorium.
Friends and former colleagues and pupils all attended after a former student put out an appeal on Facebook.
Joanna Lodge wrote: “Myself and the majority of my Facebook newsfeed were so saddened to hear of the death of our old beloved teacher.
“It breaks my heart to think such a loving, caring man was missing for a week with no-one looking for him.”
Mr Cottam, of Norton Park Crescent, Norton, Sheffield, was involved in a crash on the A61 Dronfield bypass on July 31. He suffered serious head injuries and was taken by air ambulance to the Northern General Hospital, where he later died.
But because he had no ID on him at the time of the smash he could not be identified - and nobody came forward to report him missing.
