Hedy Lamarr, a celebrated Hollywood actress, emerged as an inventor during World War II. She collaborated with composer George Antheil to devise "frequency hopping" technology. Their invention allowed radio signals to rapidly switch frequencies in a pattern known only to the transmitter and receiver, making it difficult for enemies to jam or intercept the signals. They drew inspiration from the piano roll. This enhanced the security of the communication systems and helped keep enemies from being able to detect radio-guided torpedoes.

It also laid the foundation for modern wireless communication systems. Even though she encountered skepticism and gender bias, Lamarr's invention gained recognition. The United States Navy later embraced it in the 1960s. Today, her work continues to resonate across diverse fields such as telecommunications and cybersecurity.

Letitia Geer changed the landscape of healthcare by inventing the medical syringe. She worked helping her husband make medical supplies and observed the challenges healthcare providers faced in administering medications. Geer was motivated to find a solution. She developed a novel syringe design that allowed for precise measurement and delivery of fluids. It had a glass barrel with measurement markings and a plunger. Its design allowed providers to use it with only one hand. She received a patent for her syringe in 1899 and founded the Geer Manufacturing Company to make the syringe. She also invented a nasal speculum and a retractor. Geer was also very active in the Women's Suffrage Movement.
