21. Bic Ballpoint Pen
Year Invented: 1938
Designer: Lazlo and Gyorgy Biro
Lazlo and Gyorgy Biro presented their pen design at the Budapest International Fair in 1931. By this time, many variations on the ballpoint pen had been patented, but none of these were as commercially viable as the Biros' design. The Hungarian Biro brothers panted their design in 1938, and in 1943 they moved to Argentina, where they formed Biro Pens of Argentina. The design was licensed to the British, and in 1945, Marcel Bich bought the patent, which soon became the star product of his Bic company.
