  Heaviside
Oliver W. Heaviside was born on May 18, 1850 in Camden Town, London, England, the youngest of four sons of Thomas Heaviside, an engraver and watercolorist, and Rachel Elizabeth West, a sister-in-law of the famous physicist Sir Charles Wheatstone.
Oliver Heaviside was born in a low social class of Victorian England in the same London slums as Dickens was.
In 1902, Oliver Heaviside and the American electrical engineer Arthur Edwin Kennelly independently and almost simultaneously, announced the probable existence of a layer of ionized gas high in the atmosphere that affects the propagation of radio waves.

 Oliver Heaviside Summary
Heaviside showed mathematically that uniformly distributed inductance in a telegraph line would diminish both attenuation and distortion, and that, if the inductance were great enough and the insulation resistance not too high, the circuit would be distortionless while currents of all frequencies would be equally attenuated.
Heaviside, after 1880, recast Maxwell's mathematical analysis from its original cumbersome form (also recast as quaternions) to its modern vector terminology, thereby reducing the original twenty equations in twenty unknowns down to the four differential equations in four unknowns we now know as Maxwell's equations.
Heaviside died at Torquay in Devon, and is buried in Paignton cemetery.

 Oliver Heaviside
My mother - she was a Heaviside - would speak of Oliver but until I went to school and learned about a Heaviside Layer around the Earth off which radio signals 'bounced' I knew little of him, except he was deaf and had sandy red hair and piercing eyes which frightened children.
Oliver, then 47 years old, was already well known for his work on the science of long distance telegraphy and telephone systems, and was made a Fellow of the Royal Society.
Oliver, always the odd one out on family occasions, can be seen at the rear wearing a cap and leaning against a pillar at the guard room above the castle entrance.

In 1905 Heaviside was given an honorary doctorate by the University of Göttingen.

 Prehistory of Radio Astronomy
Sir Oliver Lodge made many innovations in early radio technology, inventing a better radio detector, introducing the use of tuned circuits, and inventing the loud speaker.
Heaviside and Kennelly, in 1902, predicted that there should be an ionised layer in the upper atmosphere that would reflect radio waves.
The existence of the layer, now known as the Heaviside layer or the ionosphere, was demonstrated in the 1920s.

 IEEEVM: Oliver Heaviside
Oliver Heaviside was born in 1850 in Camden Town, a notoriously crime-ridden, lower class area of London.
Heaviside wasn’t so sure and was able to show mathematically that if everything is identical on both ends of the cable, the maximum rate must be the same in both directions.
Heaviside used his equations to show that if inductances (i.e., a small coil of wire) were added along the length of the cable, the distortion could be reduced.
