It is known that his father`s name was Samuel Christie James (James); with a high probability, however, we are not talking about the legendary auctioneer and founder of one of the most famous contemporary auctions, but an ordinary tailor.

In 1833 Christie published an article in which he described a prototype of a Wheatstone bridge; however, at the time the work went unnoticed.

Charles Wheatstone (Charles Wheatstone) told in another article of the Company on the measuring bridge in 1843-m; Wheatstone in the work referred to Christie, but the invention ultimately still got his name.
