LEGO Bricks Patented – 1958

LEGO Bricks Patented – 1958

Hundreds of billions of LEGO Bricks have been produced to date (their total number is estimated at 560 billion). 

Plastic Lego Bricks were patented on this day in 1958. It is interesting that these 1958 Bricks are still compatible with the ones produced today, even though they are over 55 years old. The man who applied for the patent was the head of the Lego company at the time – Godtfred Kirk Christiansen. He was actually the son and heir of Ole Kirk Christiansen, the famous founder of LEGO Group. The third generation of the family is currently represented by Kjeld Kirk Kristiansen – the wealthiest Dane, estimated to own wealth equaling around 7.3 billion U.S. dollars. Over time, the spelling of the family name was changed from Christiansen to Kristiansen.

It allegedly took five years to develop the material for producing modern LEGO Bricks. Acrylonitrile Butadiene Styrene (ABS) was chosen in the end. Hundreds of billions of LEGO Bricks have been produced to date (their total number is estimated at 560 billion, but is growing by tens of billions each year).
