BPH has just learnt of the passing of Sidney Ray last year and it is important we remember such significant figures from British photography. Sidney Ray, who died last year aged 85 years, was a lecturer at the Polytechnic of Central London (PCL) for many years and a respected authority on photographic optics and technology.
Born in Aberdeen, he was educated at Owen’s School, Northern Polytechnic and City University, where he gained a degree in Chemistry and a Masters in physiological optics. His career began in 1960 at Johnsons of Hendon as a photographic chemist, before he joined PCL, now the University of Westminster, in 1966. He taught on Britain’s first honours degree for photographic technology. As senior lecturer he focused on optical systems and visual perception with responsibility for applied photography on the BSc course in Photographic and Electronic Imaging Sciences.
His book High Speed Photography and Photonics was commended in the 1998 Kraszna-Krausz book awards and its follow-up Scientific Photography and Applied Imaging won the main prize in 2000. These, his Photographic Optics and others, went through multiple editions becoming standard works on their subjects. With fellow PCL luminaries Ralph Jacobson and Geoffrey Attridge he co-authored the updated [Ilford] Manual of Photography. Many of his publications appeared under the Focal Press imprint. He wrote regularly for the British Journal of Photography.
Sidney gained his Associateship of the IIP in 1967 and then its Fellowship along with two Fellowships of the Royal Photographic Society and one from the Master Photographers Association.
Sidney had a personal interest in the history of photographic optics. In 1989 he presented a paper on this area at the RPS Historical Group’s 1989 conference for photography’s sesquicentennial commemoration which is when I first met him and he was later supportive with my PhD. His work in the field of photographic optics and wider technology was recognised by the RPS in 2001 with an Honorary Fellowship.
Sidney Ray was married and had two children.
