Richard Sadler was a Coventry photographer from the post-war era until the 1990s. He worked extensively in the city, documenting its transformation after the war.
This series looks at Courtaulds, the synthetic fabric manufacturer, which was at the time an employer of 150,000 people across the UK. Coventry was it's research centre. These images show the development processes for rayon and corlene and the engineers, scientists and factory workers who developed and produced it.
