In 1932, carpenter Ole Kirk Christiansen founded his company in Billund, Denmark with the intention of encouraging creative games and creativity in children. At first, he made stepladders, however the effects of Great Depression forced him to be flexible and adapt his business model. He turned his attention on the manufacture of toys, and created one of the most adored brands.
Christiansen was a forward-thinker and quick to embrace new materials and technologies. In 1947, he became the first company in the world to acquire a plastic injection molding machine which dramatically increased the range and capabilities of Lego products. The machine enabled him to experiment and to create the Lego brick. The bricks had pegs on top and hollow bottoms that were interlocked with each one another, allowing children to create intricate structures that are far greater than those possible with the wooden blocks of previous generations.
The 1950s were a period of expansion for the company. Godtfred Kirk Christiansen’s daughter Kjeld Kirk Kristiansen joined the management team and she began to modernize the manufacturing processes of the company. The expansion included the introduction of dollhouses, furniture and minifigures as individual pieces. In 1979, the company expanded its product line to include sets of miniature astronauts and rockets. They also introduced spaceships, lunar rovers and spaceships.
In 1990 the company released three Model Team sets that were made for advanced builders. The sets contained small parts like axles, levers, gears, and other parts. They were the first Lego sets that offered the same level of realistic accuracy.
