He was the 10th son of a poor family who trained to be a carpenter. He married and had 4 sons before his wife passed away. After losing his job, he began making wooden toys to bring in money. He eventually put the toys into production and used the wood he had left over from his old business. Unfortunately, the factory was burned down after a spark ignited some wood shavings and they had to rebuild. The word LEGO is felt to be a contraction for the Danish words meaning "play well." After WWII, plastics became available for the construction of blocks and toys. The rest is history.
My son and I went to see a Nathan Sawaya exhibit at our local museum a few years ago. Nathan is a LEGO artist. He is so prolific, he spends over $100,000 every year on LEGO bricks! He has more than 1.5 million bricks in his New York studio. If you haven't checked out his website, visit and be amazed! The Art of the Brick
