Pens are writing utensils dating back to the 1st millennium China, as early Egyptians used thick reeds for pens around 300 BCE

Bird feather quills were roughly used around the 7th century,  and used until the 19th century, when John Mitchel from Birmingham, England, brought the first steel pen (which is like the quill but made of steel), which is the precursor of the Fountain pen "a cool pen mind you", as the inconvenience of constantly dipping the pen into the ink the Fountain pen was created.

As it had a type of "reservoir" of ink the first one that was most practical was made in 1884 by the American inventor L.E. Waterman.

After the 19th century, the well-known ballpoint pen was made, Lázló Bíró the person behind it patented it around 1895, known as the "biro" and was popular in Britain around 1930, after a decade it became a popular pen used around the world.

How it worked was a metal ball that was coated in ink from the pen reservoir and the ball rotated around in a socket that fast drying ink on the ball that would touch paper and the ink would hit the paper causing it to write.

Soft-tipped pens came around the 1960s and used a synthetic polymer on the tip instead of a ball, and the ink sunk into the soft tip and was used in: brush pens and markers, etc.

So the history of the pens hopefully left its mark, on history.
