Born Wilfred Gabriel Von Glehn, like so many citizens of German extraction, the family name was changed at the time of the First World War.
Wilfred Gabriel De Glehn as he became, had been educated at Brighton College before studying at the Royal College of Art and then at l’Ecole des Beaux-Arts in Paris.
He exhibited at the Paris Salon in 1891 and at the Royal Academy from 1896 through to 1951, being elected ARA in 1923 and RA in 1932. He also exhibited at the New English Arts Club, being elected a member in 1900.
De Glehn was a painter of portraits, figures and landscapes in both oils and watercolour; he travelled extensively throughout Europe and to the United States and exhibited landscapes of France, the United States, Italy and Ireland at the Royal Academy.
De Glehn was associated with the Newlyn School, painting in Cornwall in the post First World War years. He exhibited prolifically at the Royal Academy more than one hundred and eighty paintings and his work is represented in many public collections including Melbourne Royal Academy and the Tate Gallery.
