Hawkshaw the Detective was a comic strip character featured in an eponymous cartoon serial by Gus Mager from February 23, 1913, to November 12, 1922, and again from December 13, 1931, to 1952.
Hawkshaw the Detective was based on one of Mager's "monk" characters (so called because they looked a lot like monkeys), "Sherlocko the Monk," who made his first appearance in 1910. That name was scrapped after Arthur Conan Doyle, the creator of Sherlock Holmes, threatened legal action over the parodied name.
Playwright Tom Taylor's 1866 stage production, The Ticket-of-Leave Man, had starred a detective named Hawkshaw, so Mager rechristened Sherlocko the Monk as Hawkshaw the Detective when it debuted in The New York World on February 23, 1913. ~ Wikipedia
