Biography
Édouard Branly, born in 1844, was a physicist whose studies of electricity and telegraphy gave him an enduring place among French experimenters; he balanced teaching with patient laboratory investigations in Paris.
His invention of the coherer and explorations of electromagnetic waves provided critical proof-of-concept for early wireless telegraphy, a legacy that secures his role in the story of modern communication.
