Oliver Heaviside (18 May 1850 – 3 February 1925) was a self taught physicist, mathematician, and electrical engineer. Despite being fairly unknown, Heaviside had more academic contributions than almost any other person in history. His contributions include but are not limited to the Heaviside step function, operational calculus, vector calculus, the telegraphers equations, the coax cable, coining the terms reactance, impedance, and inductance, deriving the Lorenz force, proposing the existence of the ionosphere, the Poynting vector, and the currently used form of Maxwell's equations.

Biography

Oliver Heaviside was born to poverty in 1850 in the London slum of Camden Town. Camden Town is the same slum distinguished author Charles Dickens was from. Heaviside was the child of water color artist and wood engraver Thomas Heaviside and Rachel West. At a young age Oliver contracted the scarlet fever which left him partially deaf. He was a top student in all subjects except geometry; however, by the age of 16 Heaviside had dropped out of school and began to teach himself.

Despite being born of little means, Heaviside was lucky because his maternal uncle by marriage was Charles Wheatstone. Wheatstone was a well-known inventor and electrical scientist who co-invented the telegraph among other accomplishments. Wheatstone took great interest in his nephews and was likely involved with Oliver’s first job as a telegraph operator. Heaviside rapidly became the head operator for the Great Northern Telegraph company. This would be Heaviside’s only full-time employment he would ever have. Around 1873 Heaviside quit his job and begin devoting his entire life to scientific and mathematical research and development.

He began his independent work by reducing Maxwell’s equation. It was Heaviside that created the current four vector equations with two variables used to describe electric charges and induction. In addition, he made large contribution to vector calculus and created operational calculus. He also created the Heaviside step function and made large contributions in the field of electrical engineering. He suggested the use of induction coils, invented the coax cable, and coined many of the commonly used electrical terms used today. One of his other main accomplishments was the proposal of the ionosphere. Sadly Heaviside never gain recognition for any of his accomplishments.

Possibly because of lack of recognition for all of his incredible accomplishments, Heaviside became rather strange in his late life. It is reported the furniture in his home consisted mainly of large granite blocks. He also began painting his finger nails pick and ending letters with the puzzling initials “W.O.R.M” written after his signature. Heaviside died on February 3rd, 1925 a basically unknown name.
