William Crawford Eddy, American Inventor

William Crawford Eddy (August 22, 1902 - September 15, 1989) was an American inventor, explorer, Navy officer, submariner, engineer, television producer, writer, and educator amongst many other things. He was known for being a successful 20th Century Renaissance Man. Because of his poor hearing capabilities, he developed a miniature electronic set driving a vibrating element that was contained within a hand pipe he always carried. When clenched in his teeth, the pipe delivered the sounds, albeit very distorted, through his jaw to his inner ear. When in the Navy he designed a visual display for audio tracking signals for use on submarines and designed the Dolphins insigna still worn by Navy personnel today. During WWII Eddy helped develop the ETP, Electronic Training Program. Eddy volunteered to lead the development of the classification examination commonly called the Eddy Test. This test was given throught WWII and for several years thereafter as a means of identifying men with the capability and aptitude for being trained in the enlisted ranks as electronics maintenance technicians in the US Navy and US Marine Corps. In retirement, he continued as an accomplished cartoonist and visual artist, winning awards for his oil paintings, ceramic sculptures, stained glass creations, and computer-generated art. He died in 1989 at the age of 87
