The ballpoint pen was invented by Laszlo Biro in the 1930s, who was a Jewish-Hungarian journalist. During his time editing newspapers, he became very frustrated with the amount of smudging that the fountain pen caused. This made Biro determined to design a more practical pen.
The first light pen was created around 1955 as part of the Whirlwind project at MIT. During the 1960s light pens were common on graphics terminals such as the IBM 2250, and were also available for the IBM 3270 text-only terminal. The light pen was used in the early 1980s.
