Sofie Kirk Kristiansen

A fourth-generation owner of Lego, Sofie Kirk Kristiansen, her father, sister and brother together split ownership of a 75% stake in the company.

Kristiansen is not involved in the business; her brother, Thomas, serves as Lego's deputy chairman.

Her great-grandfather Ole, a carpenter, started making wooden toys in his workshop in 1932 before moving into plastic in the 1940s.

The family has a 47.5% stake in theme park operator Merlin Entertainments, which it took private with a consortium.
