Ole Kirk Christiansen

Ole Kirk Kristiansen was a Danish carpenter. In 1932, Kristiansen founded the Danish construction toy company The Lego Group. Over the course of his working life, Kristiansen developed his business from a small wood-working shop that sold household products into a wooden toy manufacturer. In 1934, he named the company Lego and defined its core principles. Lego would eventually transfer to the production of plastic bricks following the purchase of a plastic moulding injection machine in 1947. When Ole died in 1958, the management of the company transferred to his son Godtfred.
