Ballpoint Pen
The manufacture of economical, reliable ballpoint pens arose from
experimentation, modern chemistry, and the precision manufacturing
capabilities of 20th century technology. Many patents worldwide are
testaments to failed attempts at making these pens commercially viable
and widely available. The ballpoint pen went through several failures in
design throughout its early stages.The first patent on a ballpoint penwas issued on 30 October 1888, to John Loud,
a leather tanner, who was attempting to make a writing instrument that
would be able to write on his leather products, which then-common fountain pens
could not do. Loud's pen had a small rotating steel ball, held in place
by a socket. Although it could be used to mark rough surfaces such as
leather, as Loud intended, it proved to be too coarse for letter writing
and was not commercially viable.In the period between 1904 and 1946 particularly, alternatives or improvements to the fountain pen were invented.
