Ever dependable - Ballpoint pens
The first known ballpoint pen was made in 1888. Years later, in 1938, László Bíró, a Hungarian newspaper editor, with the assistance of his chemist brother George, started designing new types of pens including one with a tiny ball in its tip that was free to turn in a socket. The mechanics of the pen were simple. As the pen moved along the paper, the ball rotated, picking up ink from the ink cartridge making it appear on paper. Ballpoint pens, or ballpens as we popularly call them, have stood the test of time and are very popular even today.
