who created the ball point pen in 1944
Ballpoint pen In 1941, the Bíró brothers and a friend, Juan Jorge Meyne, fled Germany and moved to Argentina, where they formed Bíró Pens of Argentina and filed a new patent in 1943.[1] Their pen was sold in Argentina as the Birome (portmanteau of the names Bíró and Meyne), which is how ballpoint pens are still known in that country.[1] This new design was licensed by the British, who produced ballpoint pens for RAF aircrew as the Biro. Ballpoint pens were found to be more versatile than fountain pens, especially at high altitudes, where fountain pens were prone to ink-leakage.[4]
Three-point field goal The three-point line was first tested at the collegiate level in a 1945 NCAA game between Columbia and Fordham but it was not kept as a rule. At the direction of Abe Saperstein, the American Basketball League became the first basketball league to institute the rule in 1961. Its three-point line was a radius of 25 feet (7.62 m) from the baskets, except along the sides.[2] The Eastern Professional Basketball League followed in its 1963–64 season.
