Donald Beatty - wireless and China connection
After a year at Marion Military Institute, Beatty got permission from his father to enlist in the United States Navy at age 17. He was sent to the Navy Radio School set up at Harvard University. In 1919 the United Fruit Company hired him to construct and install wireless (radio) telegraphy equipment along its steamer routes in Asia. He reportedly constructed the first voice radio station in mainland China during that engagement.
