William Roger Benner's granddaughter contacted us in 2018 to let us know that he spent a considerable time in Cornwall in the years between the two World Wars. The subjects of his watercolours included fishing boats and steam engines.

Benner was a teacher at High Pavement Boy's School in Nottingham from the 1920s until the early 1950s. He continued teaching during World War II, being over the age of conscription. He retired to Blythburgh in Suffolk, where he continued to paint.
