Edward H. Thompson (1879 - 1949) was born in Cumbria and went against the wishes of his parents to become a painter. In his lifetime he painted as many as ten thousand paintings and most of them of the Lake District.
Known as Ted, he had an interest in painting from an early age when he spotting someone painting and thought he could do better than that. He eventually became a full time artist
He also painted picture postcards for Valentines of Dundee. In the 1940s Valentines reproduced the pictures in the form of booklets and also calendars, Ted's last work for Valentines appears to have been a series of idealised country cottages, in 1949 for a calendar.
