Description
In the late 1920’s, Dr. Gerhard Fisher, a German immigrant who studied electronics at the University of Dresden, obtained the first patent ever issued on aircraft radio direction finders. He was working as a Research Engineer in Los Angeles, California at the time and his work attracted the interest of Dr. Albert Einstein. After a demonstration of Dr. Fisher’s equipment, Einstein enthusiastically and correctly predicted the world-wide use of radio direction finders in the air, on land and at sea.
When using such direction finders during those early years, aircraft pilots found that errors would occur in their bearings when metal objects came between the transmitter and receiver, or whenever they passed over certain areas. Different pilots flying different planes always observed the same errors over the same places. When Dr. Fisher investigated this phenomenon, he found these errors to be the result of highly conductive, mineralized areas. Dr. Fisher concluded that a portable electronic prospecting instrument could be developed that used the same principle to detect the presence of small buried objects and ore deposits.
He continued his research into this phenomenon, and in 1931 he founded Fisher Research Laboratory in a garage behind his home at 1505 Byron St. in Palo Alto, California. He and four employees began producing the "Metallascope," starting each unit as a new order came in. The "Metallascope" was a rugged, easy-to-use metal detector. By today’s standards, it was perhaps an ungainly device: two large, flat wooden boxes containing simple copper coils, five vacuum tubes, and a few assorted components. It soon captivated the imagination of the country, and within a short time, the world.
