Career
At the time of her appointment as a professor, Blade was "the only woman on the Cooper Union engineering faculty (where she initially taught drawing, mathematics and design) and one of few women on any engineering faculty in the United States". Her obituary stated that she was the first woman professor of mechanical/electrical engineering in New York City.

Mary Blade helped organize the May 27–28, 1950 inaugural weekend of the Society of Women Engineers at Cooper Union's Green Engineering Camp.

In 1978, Blade was featured in Chair: The current state of the art, with the who, the why, and the what of it by Peter Bradford and Barbara Prete with a chapter titled "Physical Forces and Damages, Your Sitting Behavior, Move."

In 1980, the Engineering Design Graphics Division of the American Society for Engineering Education awarded Blade its Distinguished Service Award.
