Graynella Packer was an American author and attorney, best known for being the first female radiotelegraph (wireless) operator to make overnight voyages on an ocean-going vessel, when she served aboard the steamship Mohawk along the Atlantic seaboard from November 1910 to April 1911.

[2] After Packer finished college studies, she decided to go into landline telegraphy, in part due to her poor eyesight, because, in her words, "handling a key is no strain on the sight".

This interest was increased by the recent celebrated actions of operator Jack Binns aboard the Republic, who she came to see as a model for how she would respond in a crisis.

[4] There had been at least one female maritime radio operator who preceded Packer—Annie Tucker, who in 1908-1909 served on a vessel making short daily runs in the Puget Sound in the state of Washington.

[6] The ship's sole operator, Packer reported that "My berth is right in the wireless room with the little receivers near my bedside, and awake nearly once every hour to listen for messages."

Her send off was heavily covered, and after reaching Charleston she noted that "When the Mohawk was ready to leave New York, there must have been twenty-five or thirty reporters there, and there were ten camera men, all requesting me to pose for my picture."

"[9] In 1914 she graduated from a year-long Public School Music program at Albany college in Oregon,[10][11] and the next summer enrolled at the University of Washington in Seattle.

[16] By 1935 she was qualified to practice law in four states, had been elected the first woman secretary of the Bar Association of Oklahoma, and made multiple international trips, including a world tour in 1934.

She went on train herself to send and receive Morse code, and also set up an amateur radio station in order to become acquainted with operating techniques and equipment maintenance.
