Who invented pen and who invented ball oen​

Answer»

tion'-László BíróLászló Bíró first sold the ballpoint pen in 1938, just before the onset of WWII. The pen may be mightier than the SWORD, but when Jewish-Hungarian journalist László Bíró INVENTED the ballpoint pen in the 1930s clichéd sayings were probably the LAST THING on his mind.
