Marie Van Brittan Brown – CCT Security Systems

Marie Van Brittan Brown was a nurse who sometimes worked the late shift.  When she was home alone and the doorbell rang, she wanted to know who was at the door without opening it.  She worked with her husband Albert to create a closed-circuit television (CCTV) system so that she could see who was at the door without opening it. They were awarded a patent in 1969 and more recent patents for home security systems refer to their patent!

Hedy Lamarr, Technology Underlying WiFi

A famous actress, she wanted to help the US win the war in WW II and made an insight about player piano rolls that led her to work with her friend George Antheil to invent the idea of frequency hopping, that would help torpedoes hit their targets. While this technology wasn’t completed in time to help with WWII, it is the underlying concept that is used in fax machines, cell phones and wifi. Her movie studio made her keep her involvement a secret, and she did for years, until she was in her 80s!  Read our blog post about her to learn more.
