Executive summary: Kennelly-Heaviside layer

Self-taught British electrical engineer Oliver Heaviside used James Clerk Maxwell's equations to explain the functions of conductance, impedance, and self inductance (and he is believed to have coined the terms) in cable telegraphy. To explain the first successful radio broadcasts across the Atlantic Ocean in 1901, he theorized that radio waves are "caught" by a layer of the Earth's atmosphere and carried along above the planet's curvature, instead of being projected straight into space. This atmospheric layer, also predicted by American physicist Arthur E. Kennelly, is now known as the Kennelly-Heaviside layer.

Heaviside's uncle, Charles Wheatstone, invented the telegraph, and as a young man Heaviside worked as a telegrapher. His hearing was damaged by a childhood bout of scarlet fever, and his deafness grew progressively more profound as he aged, forcing him to quit working at the age of 24, after which he turned to science. Described by contemporaries as reclusive and abrasive in character, Heaviside never married or dated women but also considered men to be "horrid creatures." He apparently held himself in low esteem, as for the last decades of his life he signed most of his correspondence and papers "Oliver Heaviside, worm."
