Sir Charles Wheatstone was born on 2 February 1802 in the village of Barnwood in the United Kingdom. He was the second son of William Wheatstone, a manufacturer of musical instruments, and was taught in various schools throughout London. During his youth he would save money to purchase all types of book, including fairy tales, history and science. Wheatstone excelled in mathematics and physics, and learned French, Latin and Greek.

Wheatstone invented two new musical instruments, the Wheatstone Baritone English Concertina and the portable harmonium. The harmonium gained him a medal at the Great Exhibition in 1851.

The first description of the bridge was by Samuel Hunter Christie (1784-1865) and was published in the ''Philosophical Transactions ''in 1833.

Wheatstone had been fascinated with electrical measurements, and worked on many devices for a number of years.

Sir Charles Wheatstone was born on 2 February 1802 in the village of Barnwood in the United Kingdom. He was the second son of William Wheatstone, a manufacturer of musical instruments, and was taught in various schools throughout London. During his youth he would save money to purchase all types of book, including fairy tales, history and science. Wheatstone excelled in mathematics and physics, and learned French, Latin and Greek.

Wheatstone invented two new musical instruments, the Wheatstone Baritone English Concertina and the portable harmonium. The harmonium gained him a medal at the Great Exhibition in 1851.

However the invention that would forever be linked to Wheatstone is the Wheatstone Bridge. He publicly admitted that he did not invent it. But he did more than anyone else to advance its use when he enhanced and popularized the device in 1843.

The first description of the bridge was by Samuel Hunter Christie (1784-1865) and was published in the Philosophical Transactions in 1833.

Wheatstone had been fascinated with electrical measurements, and worked on many devices for a number of years.
