A pensioner who received "horrific injuries" when a coach crashed on the motorway near Heathrow has died six months after the incident.
John had two children by his wife Norma Carruthers
John Carruthers, 78, from Chertsey, Surrey, died in hospital on 1 July. A post-mortem examination was held but cause of death has not been confirmed.
Two people died in January when the National Express coach overturned on the slip road of the M4/M25.
The coach driver was arrested by police and bailed to return later this month.
In a police statement, Mr Carruthers family said: "His sense of fairness, consideration for others and sense of humour never left him, even after the accident and his horrific injuries, and in intensive care he would joke with the nurses."
"He remained positive and worked hard to regain his fitness, intending to drive and play golf again."
Mr Carruthers was born in Glasgow and after school became a research chemist for BP in Hamburg, Germany.
He was a keen golfer and enjoyed Scottish dancing and ran the local society for many years.
Mr Carruthers had two daughters and five grandchildren.
