Who founded the Lego Group?

Ole Kirk Christiansen founded the LEGO Group.

A carpenter and joiner in Billund, Denmark, Christiansen began making wooden toys in 1932 during the economic crisis. His early products included practical wooden goods as well as toys, but the toy business gradually became the company's central focus. The company later adopted the LEGO name, derived from the Danish words leg godt, meaning “play well.”

Christiansen's business eventually moved into plastic construction toys. In 1949, the company introduced an early form of the modern LEGO brick, and the interlocking brick design familiar today was patented in 1958. His son Godtfred Kirk Christiansen helped develop the LEGO System in Play and later led the company.

The family names in the alternatives can cause confusion because LEGO remained family-owned across generations. Godtfred was the founder's son, Kjeld was his grandson, and Jørgen Vig Knudstorp later became a prominent executive—not the person who established the company.
