1949 __ History of Magnetic Recording
Comment : [This] history was written by Semi J. Begun who pioneered magnetic tape recording at the Brush Development Company in Cleveland, Ohio. Begun immigrated from Germany in 1938 where he had developed a steel-tape recorder for the C. Lorenz Company. In 1939, he led the research program at Brush Development that produced recording equipment for the U. S. military in World War II. In the first chapter of the book Semi J. Begun wrote in 1949 on magnetic recording: “Myth and folklore abound with tales of how the human voice has been captured or preserved, but the only known early attempts to realize this idea were the efforts to construct mechanical devices which would "talk." As early as the third century B.C., Heron of Alexandria is said to have devised automata which would talk or emit the cries of animals. The earliest such device of which we have any actual knowledge is the one constructed by De Kempelein of Vienna, who, in 1791, published a description of it under the title "The Mechanism of Speech, Followed by a Description of a Talking Machine." De Kempelein's device could be made to speak short sentences. [...]”.
