String galvanometer
In the late 1800s, telegraphy was developing as a way for distant communication. Messages were converted to dots and dashes that were sent as electric pulses and could be converted to sound or visual signals at the distant site. That conversion was done by a coil in a galvanometer, which had a limited frequency. Clément Adair, a French engineer, replaced the coil with a much faster wire or "string" producing the first string galvanometer. Augustus Waller had discovered electrical activity from the heart and produced the first electrocardiogram in 1887. But his equipment was slow. Physiologists worked to find a better instrument.
