Orlando R. Marsh (August 6, 1881 – September 7, 1938)[1] was an electrical engineer raised in Wilmette, Illinois.
His firm Marsh Laboratories, Inc., founded in 1922,[2] at one time was located on the seventh floor of the Lyon & Healy Building near the corner of Wabash and Jackson in Chicago.
(1) It was reported in Time Magazine on April 28, 1923 that a device invented by Orlando R. Marsh was successfully used to make a recording of organ music, hitherto considered impossible.
The article stated that Pietro A. Yon from New York City played his organ composition "Jesu Bambino" in Marsh's Chicago laboratory and that the reproduction was described as excellent.
Freeman Gosden and Charles Correll electrically recorded their WMAQ (AM) Amos 'n' Andy radio program at Marsh Laboratories prior to live airing during the 1928 - 1929 period.
