The ballpoint pen invented by Ladislao Jose Biro was originally patented in Hungary in 1938. The principle of the ballpoint pen was originally patented by John Loud in 1888 for a product to mark leather and in 1916 by Van Vechten Riesberg, but neither of these products were exploited commercially.
As a journalist, Biro was inspired by the concept of quick-drying ink in a print shop.
