His Douglas Convolution science fiction series concerns the breakdown of civilization after most of a generation is born sterile as a side effect of a widely used anti-cancer medication.
Born in Salisbury, England, Llewellyn-Thomas graduated with a degree in electrical engineering from the University of London shortly before the start of World War II.
As a specialist in radar and communications he served with the Royal Electrical and Mechanical Engineers and saw action in North Africa and the Far East.
Following graduation from McGill, he interned at the Queen Elizabeth Hospital in Montreal and during that time decided to work as a general practitioner in a small community, in order to experience as much as he could of the breadth of the practice of medicine.
It was during this time that he also worked as a Research Associate in the Department of Social Psychiatry of Cornell University, taking part in a major project designed to study psychiatric illness in small communities.
An opportunity to work on man and the environment related to aerospace medicine attracted him, and the family moved to Toronto in 1958, where he joined the Defense Research Medical Laboratory.
He used this to study eye movements under a variety of physical conditions, such as driving an automobile, flying a small aeroplane, or perusing art.
Subsequent to his appointment as associate director of the then Institute of Biomedical Electronics, a picture of a much improved version of this camera was used as the front-cover for an issue of Scientific American (August 1968).
In this issue, he was the author of a full description of the camera design and its application in a variety of studies that he and his graduate students at the Institute continued to conduct.
In this capacity he provided a direct link to the Faculty of Medicine as well as to the associated medical research groups in the surrounding hospitals.
Edward Llewellyn-Thomas died 5 July 1984, only a few days after his retirement as Associate Dean for Student Affairs, Faculty of Medicine, University of Toronto.
