The LEGO Group was founded in 1932 by Ole Kirk Christiansen, and has passed from father to son and is now owned by Kjeld Kirk Kristiansen, a grandchild of the founder.
Over the 70 years, it has come from a small carpenter's workshop to a modern, global enterprise that is now, in terms of sales, the world's sixth-largest manufacturer of toys.
