Who designed the HD Logo for Hd?

The abbreviation HD can mean a number of things, so it's hard to define who designed its logo. For motorcycle enthusiasts, HD means Harley-Davidson; the Harley Logo was designed in 1910 but it's unclear who gets the credit for the idea. HD can also refer to high definition, a desirable characteristic in video equipment today. While many products are emblazoned with an HD logo, the design varies from one company to the next and there is no standard HD logo.
