The Swedish founder of the Ikea furniture chain, Ingvar Kamprad, has died at the age of 91, the company has announced.
Mr Kamprad - who pioneered flat-pack furniture - died at his home in Sm?land, Ikea confirmed in a statement.
The company said that Mr Kamprad was "one of the greatest entrepreneurs of the 20th century".
The billionaire, who was born in 1926 in Sm?land, founded Ikea at the age of 17.
He used some money his father had given him as a gift for performing well at school despite his dyslexia.
In a statement on Sunday, Ikea said that Mr Kamprad had "peacefully passed away at his home".
"He worked until the very end of his life, staying true to his own motto that most things remain to be done," it added. Mr Kamprad eventually stepped down from the company’s board in 2013, at the age of 87.
His company’s designs became popular in part because of their simplicity and value.
Furniture designer Jeff Banks said that Mr Kamprad’s creations radically changed how people made and designed products for the home.
Mr Kamprad was renowned for his devotion to frugality, reportedly driving an old Volvo and travelling by economy class.
In a 2016 interview with Swedish television channel TV4, Mr Kamprad said that it was "in the nature of Sm?land to be thrifty".
"If you look at me now, I don’t think I’m wearing anything that wasn’t bought at a flea market," he said.
People took to social media on Sunday to pay their respects to the "greatest Swedish entrepreneur to have ever lived".
Swedish Foreign Minister Margot Wallstrom tweeted her condolences, saying that Mr Kamprad had "put Sweden on the world map".
