George Trevor Hollingworth has died at his home in Skipton at the age of 81.
A former consultant physician in psychological medicine, Mr Hollingworth, who went by his middle name Trevor, received training in London, qualifying at the Royal Free Hospital where he obtained double honours.
He spent two years at the Institute of Diseases of the Chest before joining the National Hospital, Queens Square.
During his neurology training there, he met Elliot Slater, who thought training in psychiatry at the Maudsley Hospital would complete his already wide-based studies.
Following his Maudsley training under Sir Aubrey Lewis, he became senior registrar in psychiatry at Westminster Hospital before opening and developing a district service at Airedale General Hospital in Steeton.
Following his retirement from medicine, he became an active trader on the stock markets to which he applied his psychological training, finding it almost as interesting as medicine.
A private funeral service has been held in Skipton.
