Writing as: G. H. Teed, George Hamilton Teed
According to Wikipedia: "George Hamilton Teed (9 December 1886 – 24 December 1938) was a Canadian author who also wrote under the pen-names G. H. Teed, Hamilton Teed, Louis Brittany, Peter Kingsland, and Desmond Reid. Teed was born in Woodstock, New Brunswick. He specialized in adventure fiction and detective stories, but also wrote science fiction and the odd romance. He is best remembered for his tales of Sexton Blake, a popular, fictional British detective who featured in a wide variety of publications in the first half of the twentieth century. He wrote close to three hundred Blake tales, more than any other author, and his creations and writings are considered 'the best in Blake history before the Second World War.'"
Note: Al Hubin's excellent Crime Fiction IV lists his middle name as 'Heber', not 'Hamilton'.
