IKEA stands for: Ingvar Kamprad, the founder, Elmtaryd, the farm he grew up from, and Agunnaryd, the town he came from. He started his business when he was 17, selling small furniture objects (picture frames, etc.).
IKEAS founder's grandmother was once a supporter of Hitler. This naturally influenced the founder who then also supported Nazis for a time. Since then he has admitted his mistakes and even sent a handwritten letter to employees, hoping they would forgive him.

This was due to Kamprad's dyslexia (a reading disorder), where numbering the products would have made them harder to read.
