Ole Kirk Christiansen, Danish businessman, founded the Lego Group (died 1958)

Ole Kirk Christiansen was a Danish carpenter. In 1932, he founded the construction toy company Lego, later known as The Lego Group. Christiansen transformed his small woodworking shop, which initially sold household products, into a manufacturer of wooden toys. By 1934, he had officially named the company Lego and established its fundamental principles. The business shifted to producing plastic bricks after the acquisition of a plastic moulding injection machine in 1947. Following his death in 1958, the company's management was handed over to his son, Godtfred.

Lego A/S, also known as the Lego Group, is a Danish construction toy production company based in Billund. It manufactures Lego-branded toys, consisting mostly of interlocking ABS plastic and rubber bricks. The Lego Group has also built several amusement parks around the world, each known as Legoland, and operates numerous retail stores.
