Paul Frederick Ernst was an American pulp fiction writer. He is best known as the author of the original 24 "Avenger" novels, published by Street & Smith under the house name Kenneth Robeson.
He "[took] up fiction writing in his early twenties." Credited by pulp-expert Don Hutchison as "a prolific manufacturer of potboilers-made-to-order," his stories appeared in a number of early Science fiction and fantasy magazines. His writing appeared in Astounding Stories, Strange Tales and Amazing, and he was the author of the Doctor Satan series which ran in Weird Tales from August, 1935. His most famous work was in writing the original 24 The Avenger stories in the eponymous magazine between 1939 and 1942.
