The QWERTY (named for the key placement of the upper left row) was invented by Christopher L. Sholes, who began its development in 1867

(This keyboard was designed to be as inefficient as possible because if people typed too fast the typewriter would jam. So Sholes arranged the keys so that many words would be typed with only one hand, few words can be typed on the home row, and the left hand gets the majority of the work.

The DVORAK keyboard, which uses a different setup, improves efficiency by at least 70%, but like many good ideas it never caught on.)
