⌨️ The Complete History and Evolution of Keyboards

🧩 1. Basic Overview

First Developed By: Christopher Latham Sholes
Invention Year: 1868
Original Device: Typewriter (Remington No. 1)
Technology Evolution: Typewriter → Teletype → Early Computer Keyboards → Modern Keyboards

The journey of the keyboard began in the 19th century with the invention of the typewriter by Christopher Latham Sholes in 1868, which laid the foundation for modern typing devices. The QWERTY layout created then remains dominant today.
