Ole Kirk Christiansen

Ole Kirk Christiansen is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Ole Kirk Christiansen rather than just read about it. In short: Ole Kirk Christiansen (born Ole Kirk Kristiansen; 7 April 1891 – 11 March 1958) was a Danish carpenter. In 1932, he founded the construction toy company Lego, later known as the Lego Group.

Key takeaways

  • Ole Kirk Christiansen belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Ole Kirk Christiansen to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Ole Kirk Christiansen from memory before moving on to harder problems.

Reference excerpt

Ole Kirk Christiansen (born Ole Kirk Kristiansen; 7 April 1891 – 11 March 1958) was a Danish carpenter. In 1932, he founded the construction toy company Lego, later known as the Lego Group. Christiansen transformed his small woodworking shop, which initially sold household products, into a manufacturer of wooden toys. By 1934, he had officially named the company Lego and established its fundamental principles. The business shifted to producing plastic bricks after the acquisition of a plastic moulding injection machine in 1947. Following his death in 1958, the company's management was handed over to his son, Godtfred.

Early years Christiansen was born on 7 April 1891 in Omvraa Mark, Filskov, South Jutland, Denmark, which is 20 km northwest of Billund. He was one of 13 children of a farm labourer. His parents were Jens Niels Christiansen and Kirstine Christiansen. Although his family was poor, Christiansen was able to receive a basic high-school education. It was while he was working as a farmhand from the age of six that Christiansen developed a fascination with whittling wood, in between the two days per week that he attended school. In 1905, when Christiansen was 14, he began working as an apprentice for his older brother, Kristian Bonde Christiansen. In 1911, after his apprenticeship, he served in the military and studied at Haslev Technical School. After, he travelled abroad and went to work in carpentry in Germany and Norway before returning to Denmark.

Wood-working business In 1916, Christiansen returned to Denmark and settled in Billund. He bought a carpentry shop with the money he had saved and named it Billund Maskinsnedkeri og Tømreforretning (Billund Woodworking and Carpentry Shop). During the late 1920s, the business focused on restoring and developing new buildings and also producing household goods for the local community. In 1924, Christiansen's business was almost destroyed when his sons, Karl Georg and Godtfred, caused a fire to break out by accidentally setting fire to wood shavings in the workshop while trying to light a hot glue machine. Consequently, both the workshop and the family home burned down. Following this event, Christiansen decided to expand his business and employed an architect to build a larger workshop and family home. The construction of the house, which is situated on Hovedgaden in Billund, was completed in 1924 with two stone lions placed at its entrance. By 1930, Christiansen employed a small workforce to maintain his growing business.

Family and personal life While establishing his business, Christiansen met Kirstine Sörensen, the daughter of a local cheese-maker. They married in 1916 and had four children. Sörensen died in 1932 after the birth of their fourth child. Two years later, Christiansen married Sofie Jörgensen and they had one daughter. Christiansen was a member of the Church Association for the Inner Mission in Denmark.

Beginnings of Lego

During the early 1930s, Christiansen's business was impacted by the onset of the Great Depression in Denmark. The drop in farming prices resulted in many of his customers being unable to afford his products. This decline in business forced Christiansen to lay off staff in early 1932 until only seven employees remained. The primary income, which was from sales of ladders and ironing boards, was shrinking in demand. Eventually, Christiansen had to dismiss his last worker. In order to sell more products, he made the decision to produce cheap wooden products, including wooden toys. With the business slipping into bankruptcy, he refused to stop producing toys when his siblings requested this as part of a bailout loan. He decided to officially found an unnamed company (later to become Lego) in 1932. Christiansen's company moved primarily to the production of wooden toys, such as yo-yos, pull-along animals and trucks. He consequently decided to focus his products on the development of children. With this decision, Christiansen defined the core philosophy of the company, which was expressed in its name in 1934. Lego is a shortened form of the Danish word Leg godt, meaning "play well". The company eventually became known as The Lego Group. Years later, he said, "Not until the day when I said to myself, 'You must make a choice between carpentry and toys' did I find the real answer." Christiansen made his toy products from birch wood that had been cut from the forest, dried out for two years and then dried in a kiln for three weeks. The toys were put together, sealed, sanded and primed before being painted with three coats of varnish. Although he struggled to sell his household products and wooden toys due to the poverty levels of people living in the local community, he continued to produce toys, sometimes exchanging them for food. By 1935, the toy range included a variety of animals, including a pull-along wooden duck, which has since seen numerous variations.

Worked examples

Example 1 — a first encounter with Ole Kirk Christiansen

Start with the simplest possible case. Write down what Ole Kirk Christiansen claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Ole Kirk Christiansen before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Ole Kirk Christiansen ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Ole Kirk Christiansen

In research
Ole Kirk Christiansen appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Ole Kirk Christiansen in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Ole Kirk Christiansen is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1891 births, 1958 deaths, 20th-century Danish businesspeople, so understanding it makes those chapters shorter.
In everyday life
Look for Ole Kirk Christiansen outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
