Everything about Sidney Bradford totally explained
Sidney Bradford (
May 30,
1906 -
August 2,
1960) went
blind at 10 months of age but regained sight on both eyes after a
cornea transplant at the age of 52. He was the subject of many scientific studies of perception by
neuropsychologist Richard Gregory.
His operation was able to reveal idiosyncrasies of the human visual system. For example, not having grown up with vision, Bradford didn't perceive the ambiguity of the
Necker cube. Nor was he able to interpret the
perspective of two-dimensional art.
Nevertheless, he could accurately judge the distance to objects in the same room, having been familiar with these distances before regaining sight by virtue of having walked them. In a similar analogy between vision and sightless (touch-only) experience, Bradford was able to visually read the time on the ward
clock just after his operation.
Intoxicated with a new world of colour and motion Bradford became terrified of the sights that he could not, in many cases, understand. He couldn't recognise humans, or many items he'd hitherto perceived only by touch.
Before surgery Bradford was a skilled machinist, but upon gaining vision, he became confused and unable to work. He committed suicide two years after his operation.
