David Mason is an Art dealer with two galleries in London St. James’s.  He is married with four children. 

David Mason fought the Thalidomide Campaign against Distillers in the 1970s to obtain compensation for all the victims of the drug Thalidomide.  His first daughter was a victim.  He went on to fight the Opren Campaign in 1977 obtaining increased compensation.

His other charitable work includes founding the British Equestrian Olympic Fund which raised funds for the British Equestrian Olympic Team to take part in the Montreal Olympics in 1976. Chairman of the Gunnar Nilsson Cancer Treatment Research Campaign (Gunnar Nilsson was a Formula One driver) to raise funds to build the Gunnar Nilsson Wing at the Charing Cross Hospital assisted by Sir Jackie Stewart, Mario Andretti and Prince Bertil of Sweden.

Founding Chairman of the Oxford Transplant Campaign in 2006 to raise funds for the new wing and equipment at the Oxford Transplant Centre at the Churchill Hospital.

The reason for such an active involvement with the Oxford Transplant Unit was the appreciation and realisation that the unit is without doubt the centre of excellence and in the opinion of many probably unparalleled.  Within this unit there is great leadership and knowledge by gifted doctors, surgeons and specialists in this field that deserve every bit of help possible.  They really are quite outstanding.
