Francis Ronalds

Sir Francis Ronalds (21 February 1788 – 8 August 1873) was an English scientist and inventor, sometimes described as the first electrical engineer. He was knighted for creating the first working electric telegraph over a substantial distance. In 1816 he laid an 8-mile (13 km) length of iron wire between wooden frames in his mother's garden and sent pulses using electrostatic generators. He also created the first electric clock in 1814.
