Shown here a hundred years ago today, in the August 9, 1925, issue of the San Antonio (TX) Light is Miss Annie Bommer of 312 Frasch Street, San Antonio.

Even though she was still in her teens, she thought nothing of building this five-tube TRF receiver with a regenerative detector.

She had three years experience in radio, starting with a crystal set, and had worked her way up to more complex sets. She was also skilled at automobile mechanics, the result of chumming around with her brothers. She had been put in charge of the radio department at Grant’s Department Store and the size of the department had greatly increased under her management.
