1850 – Heaviside – bio

Oliver Heaviside was born in London in 1850 and was a mathematician and electrical engineer. He started out as a telegraph operator then began publishing research papers on telegraphy and made contributions to the electromagnetic principles involved in telegraph line transmission. He adapted Maxwell’s equations to create a pair of linear differential equations that describe how voltage and current vary over time and distance in transmission lines. He patented an idea for coaxial cable in 1880. In 1884, he reworked Maxwell’s equations in a vector framework. In the course of doing this, he created a method of solving differential equations known as operational calculus.
