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 In the 1979–80 season, after having tested it in the previous pre-season, the NBA adopted the three-point line despite the view of many that it was a gimmick.[4] Chris Ford of the Boston Celtics is widely credited with making the first three-point shot in NBA history on October 12, 1979. Kevin Grevey of the Washington Bullets also made one on the same day.
