Question: how the qwerty keyboard layout came to be?
Answer: QWERTY (/ˈkwɜːrti/) is a keyboard design for Latin-script alphabets. The name comes from the order of the first six keys on the top left letter row of the keyboard ( Q W E R T Y ). The QWERTY design is based on a layout created for the Sholes and Glidden typewriter and sold to E. Remington and Sons in 1873.
