Christopher Latham Shole invented the QWERTY keyboard arrangement, making it the first letters in modern keyboards.
Prior to the 1870s when Shole changed the keyboard arrangement, letters on the keyboard were arranged in alphabetical order.
Currently, the alphabet starts with QWERTY on a typewriter, computer keyboard, and obviously on a smartphone keyboard.
Why did Shole changed the keyboard arrangement?
Christopher Latham Shole discovered that the action of the typebars in early typewriters was sluggish, and tended to jam frequently.
To solve this problem, Shole obtained a list of the most common letters used in English and changed his keyboard from an alphabetic arrangement.
Christopher Latham Shole is credited for developing the first practical typewriter. His typewriter was marketed by Remington Arms Company in 1873.
