For those who travel via airplane, give a big thank you to the late Miriam Benjamin. In 1888, she received a patent for her invention, the “Gong and Signal Chair for Hotels, “ a precursor to the modern flight attendant signaling system.
The invention featured a button that would buzz to alert hotel staff if a patron needed service, and the chair had a light that was activated when the button was pressed. Benjamin’s intention was to reduce wait time for attendant staff at hotels. There is some speculation, however, that Benjamin created the device for her classrooms to create order during instruction.
