Ole Kirk Christiansen, a carpenter from Billund in Denmark, founded his company in 1932, with the intention of encouraging imaginative play and imagination in children. At first, he made stepladders, however, the effects of the Great Depression forced him to be flexible and modify his business model. He switched his focus to manufacturing toys, and in the process he established one of the most loved brands in the history of the world.
Christiansen was a nimble thinker and quick to adopt new materials and technologies. In 1947 he was the first company to acquire a plastic injection molding machine, which greatly increased the options and capabilities of Lego products. The machine allowed him to explore and create the Lego brick. The bricks were hollow at the bottom and had pegs on the top. They were interlocked to let children build intricate structures that were more complex than those created with wooden blocks from earlier generations.
The 1950s were a time of growth for the company. Kjeld Kirk Christiansen, Godtfred Christiansen’s daughter, joined the management team and commenced modernizing the manufacturing processes of the company. The expansion also included the introduction of a line of dollhouses and furniture for girls, as well as the very first minifigures that were sold as individual pieces. In 1979, the company branched out into space with sets presenting astronaut minifigures and rockets, lunar rovers, and spaceships in addition to the medieval realm with a Castle theme.
In 1990, the company released three Model Team Sets that were designed for builders with advanced skills. These sets included small parts such as levers, axles, gears, and other parts. They were the first Lego sets to offer the same level of realistic accuracy.
