[Ans] Who created the ballpoint pen in 1944?

Step 1 : Introduction to the question "Who created the ballpoint pen in 1944?"

...A ball point pen is a pen that uses a small rotating ball made of brass, steel, or tungsten carbide to disperse ink as you write. All of the pens that preceded the ballpoint -- whether quill, metal or fountain -- used a watery, dark india ink that fed through the pen using capillary action. How does a ball point pen work?

 Why was the ballpoint pen invented? The first patent for a ballpoint pen was issued on 30 October 1888, to John J. Loud, who was attempting to make a writing instrument that would be able to write "on rough surfaces-such as wood, coarse wrapping-paper, and other articles" which then-common fountain pens could not.

Step 2 : Answer to the question "Who created the ballpoint pen in 1944?"

Laszlo Biro:

The first man to develop and launch a ball-point pen was the Hungarian László Jozsef Bíró, who invented a ball-point pen with a pressurized ink cartridge. He is considered the inventor of today's ball-point pen. Biro noticed that the ink used in newspaper printing dried quickly, leaving the paper dry and smudge-free. Since the thicker ink would not flow from a regular pen nib, he fitted his pen with a tiny ball bearing in its tip. Moving along the paper, the ball rotates picking up ink from the ink cartridge and leaving it on the paper. This principle of the ballpoint pen dates back to a never commercially exploited patent of 1888 owned by John J. Loud for a product to mark leather.
