UEDEMANN CODE

The code is named after its inventor, Louis Uedemann. It is a method of notation used to transmit chess moves by telegraph and is based on a system whereby each square on the chess board is designed by two letters. Each move is therefore designated by four letters: the first two are indicating the square from which a piece moves, and the last two letters reveal the square to which it moves. Years later, it was discovered that the Uedemann code was the name incorrectly given to the Gringmuth Notation. The code invented by Uedemann was never used because it was impractical.
