Oliver Heaviside FRS (1850-1925) was a brilliant self-taught electrical engineer, physicist and mathematician. Published in 1893, this is the first of three volumes that summarise his work on electromagnetic theory. It gives his first description of vector analysis and reinterprets Maxwell's field equations into the form we know today.

Published separately in 1893, 1899 and 1912, these three volumes bring together Oliver Heaviside's extraordinary contributions to electromagnetic theory.
