A shoemaker's apprentice who invented electromagnet, electrometer & a galvanometer


William Sturgeon (22 May 1783 – 4 December 1850) was an English physicist and inventor who made the first electromagnets, and invented the first practical English electric motor. Sturgeon was born in Whittington, near Carnforth, Lancashire, and apprenticed to a shoemaker. He joined the army in 1802 and taught himself mathematics and physics.
