Marie (Mrs. Robert) Zimmerman - The first woman to own and operate a radio station.

Sybil Herrold - Wife of pioneer Charles "Doc" Herrold. She was so adept at Morse Code that she taught courses at the Herrold College of Wireless in San Jose. She was also on the air at her husband's station, playing phonograph records and doing some announcing, as early as 1912.

Vaughn DeLeath - known as the "Original Radio Girl" because she sang for several of Lee DeForest's demonstrations of radio beginning in January 1920.

Eunice Randall - one of the earliest female engineers, she not only ran her own amateur station (which she built) but went on to be perhaps the first female announcer in Boston, on the AMRAD station 1XE (later WGI) around 1918.

Bertha Brainard - First female announcer in New York, she was on the air at WJZ in 1921, doing a nightly program of theatre reviews and commentary called "Broadcasting Broadway".

Mary Texanna Loomis - the first woman to become director of a radio school, she ran the College of Radio Engineering in Washington DC in the early 1920s. She was cousin to Mahlon Loomis.

Several women became program managers (what would today be called Program Directors), including Vaughn DeLeath (WDT in New York, in 1923) and Eleanor Poehler (WLAG in Minneapolis, 1922). Bertha Brainard was probably the first female network executive, being promoted to a management post with NBC Blue in late 1927.
