Sir Francis Ronalds FRS (21 February 1788 – 8 August 1873) was an English scientist and inventor, and arguably the first electrical engineer.[1] He was knighted for creating the first working electric telegraph over a substantial distance.[2] In 1816 he laid an eight-mile length of iron wire between wooden frames in his mother's garden and sent pulses using electrostatic generators.
