The Irish artist Bill Glenn was born in Belfast and had his first drawing published at the age of 16 in Saturday Night. He was then employed as an illustrator with the publishing house Graham & Heslip Ltd for a period of five years. In May 1926 he created his own comic strip, 'Oscar' for the Belfast Telegraph. The strip was also syndicated in South Africa and Australia.
Glenn stayed with the Telegraph until 1936, when he moved over to the Daily Mail in London. For this paper he created the comic strip 'Dorothea' about an attractive young woman inspired by his wife. This comic, that ran until 1939, was also published in South Africa and Australia. St. John Glenn's cartooning career was put on hold between 1940 and 1945, due to his recovery from brain surgery and his employment with the Ministry of Information during the war.
He returned to the Daily Mail as Features Editor in 1945 and initiated the Strip Cartoons Department and commissioned artists and photographers. He illustrated for The Daily Mail Annual for Boys and Girls and designed covers for the Teddy Tail Annuals. He also drew the 'Teddy Tail' strip for the paper until it's end in 1960.
From 1928, St. John also contributed cartoons to the humorous monthly Dublin Opinion. It was for this magazine that he created his first 'Ballyscunnion' cartoons, about an imaginary village in Ireland. 'Ballyscunnion' appeared in scraperboard from 1938 and was continued until 1969. Bill Glenn was also Vice-President for the Ulster Academy of Art.
