Ole Kirk Christiansen, a carpenter from Billund in Denmark founded his company in 1932 with the goal of encouraging imaginative play and a sense of wonder in children. He started by making stepladders. However, the Great Depression forced him into a flexible business model. He turned his attention to manufacturing toys, and he created one of the most popular brands in history.

Christiansen was a naive man who was quick to embrace new materials and technologies. In 1947, he became the first company to purchase a plastics injection molding machine in the world. This greatly enhanced the capabilities and selection of Lego products. The machine also let him test a design that would later become the iconic Lego brick. The bricks featured pegs on top and hollow bottoms that interlocked with each one another, allowing children to build complex structures that went beyond the possibilities of wooden blocks of previous generations.

The 1950s were a time of growth for the company. Godtfred Kirk Christiansen’s daughter Kjeld Kirk Kristiansen was a member of the management staff, and she began to modernize the manufacturing process of the company. The expansion also included the introduction of a line of dollhouses and furniture for girls, and the first Minifigures as individual figures. In 1979 the company expanded into space with sets featuring astronaut minifigures, rockets, lunar rovers, spaceships and more in addition to the medieval world with a castle theme.

In 1990, the company introduced three Model Team sets that were designed for advanced builders. These sets contained small pieces like axles, levers, gears and other components. They were the first Lego sets to provide the realism and precision.
