content: The Zenith Model 75 was a one unit vacuum tube hearing aid introduced in March 1948. Some ads touted it as an “improved kind of hearing aid that needs no ‘fitting’.” Others noted that the correctness of its underlying principle “was recently confirmed in U.S. Government-sponsored research at Harvard University.” Zenith donated this example to the Smithsonian in 1955, noting that it incorporated “important war-born electronic advances.”.
