Ingvar Kamprad & family

Kamprad was born in Pjätteryd (now part of Älmhult Municipality), Kronobergs län, in Småland, Sweden, to Feodor Kamprad (1893–1984) and Berta née Nilsson (1903–1956). His mother was of Swedish origin, while his Father was born in Germany and came to Sweden aged one with his parents. Kamprad's paternal grandfather Achim Erdmann Kamprad was originally from Altenburger Land in Thuringia, and his paternal grandmother Franzisca ("Fanny") Glatz was born in Radonitz (Radonice) in Bohemia in then-Austria-Hungary; they left Germany for Sweden in 1896.

In 1943, when he was 17, Kamprad founded IKEA in Sweden, selling replicas of his uncle Ernst's kitchen table. In 1948, Kamprad Diversified his portfolio, adding furniture. His Business was mostly mail order. The acronym IKEA is made up of the initials of his name (Ingvar Kamprad) plus those of Elmtaryd, the family farm where he was born, and the nearby village Agunnaryd where he was raised.

Kamprad and his first wife Kerstin Wadling adopted a daughter, Annika. In the 1960s, Kamprad married his second wife, Margaretha Kamprad-Stennert (1940–2011), whom he met when she was twenty years old. They had three sons: Peter, Jonas and Mathias.

He lived in Épalinges, Switzerland, from 1976 to 2014. Kamprad moved back to Småland in Sweden in March 2014 after 40 years abroad. While working with furniture manufacturers in Poland earlier in his career, Kamprad became an alcoholic. In 2004 he said that his drinking was under control, and according to The New York Times, Kamprad "controlled it by drying out three times a year".

According to an interview with TSR, the French-language Swiss TV broadcaster, Kamprad drove a 1993 Volvo 240, flew only economy class, and encouraged IKEA employees to use both sides of pieces of paper. He reportedly recycled tea bags and was known to pocket the salt and pepper packets at restaurants. Kamprad had also been known to visit IKEA for a "cheap meal". He was known for purchasing Christmas paper and presents in post-Christmas sales. The company he created is still known for the attention it gives to cost control, operational details and continuous product development, allowing it to lower its prices by an average of 2–3% over the decade to 2010, while continuing its global expansion. Kamprad explains his social philosophy in his Testament of a Furniture Dealer: "It is not only for cost reasons that we avoid the luxury hotels. We don't need flashy cars, impressive titles, uniforms or other status symbols. We rely on our strength and our will!" Kamprad owned a villa in Switzerland, a large country estate in Sweden and a vineyard in Provence, France. Kamprad was also known for driving a Porsche for several years.

Kamprad devoted two chapters to this time in Nysvenska Rörelsen in his book Leading by Design: The IKEA Story and, in a 1994 letter to IKEA employees, called his affiliation with the organization the "greatest mistake of his life". Kamprad explained his teenage engagement in New Swedish Movement as being politically influenced by his Father and grandmother in Sudet-Germany. In 2011, Journalist Elisabeth Åsbrink revealed that by 1943 the Swedish Security Service had created a file on Kamprad entitled "Nazi", and that Kamprad had told her in an interview in 2010 that: "Per Engdahl is a great man, and I will maintain that as long as I live".

According to an article in the Swedish Business weekly Veckans Affärer in 2004, Kamprad was one of the world's wealthiest people. This report was based on the assumption that Kamprad owned the entire company, an approach both IKEA and the Kamprad family rejected. Kamprad retained little direct ownership in the company, having transferred his interest to Stichting INGKA Foundation and INGKA Holding as part of a complex tax sheltering scheme that leaves his actual degree of control vague.

The Dutch-registered Stichting INGKA Foundation is named after Ingvar Kamprad (i.e., ING + KA) which owns INGKA Holding, the parent company for all IKEA stores. In May 2006 the charitable foundation was reported by The Economist to be the world's wealthiest charity, however the Bill & Melinda Gates Foundation has since become larger. Despite its large endowment its primary purpose is corporate tax-minimisation and anti-takeover protection for IKEA. Kamprad was chairman of the foundation.

In March 2010, Forbes magazine estimated Kamprad's fortune at US$23 billion, making him the eleventh richest person in the world. A year later, he fell to 162nd after his lawyers produced documents proving that the foundation he established and heads in Liechtenstein owns IKEA, and that its bylaws bar him and his family from benefiting from its funds. In June 2015, Kamprad was listed as the eighth wealthiest person in the world in the Bloomberg Billionaires Index, with an estimated net worth of $58.7 billion. Forbes reported Kamprad's net worth as of February 2016 to be $3.4 billion.

Writing in The Daily Telegraph in August 2011, Richard Orange noted that the 1943 file proved for the first time that Kamprad "was an active member of Svensk Socialistisk Samling — the successor to the Swedish Nationalist Socialist Workers Party — even detailing his membership number, 4013. It quotes letters intercepted from Mr Kamprad, then 17, in which he enthuses about recruiting new members and says that he 'misses no opportunity to work for the movement'". Orange added, "The secret Service concluded that, as Mr Kamprad received the party's youth newspaper, he must have held 'some sort of official position within the organisation'". The following day, the BBC reported: "A Swedish expert on far-right extremism, Anna-Lena Lodenius, told Radio Sweden that Mr Kamprad's Nazi involvement could no longer be dismissed as the by-product of an accidental friendship with Per Engdahl. His involvement in another fascist organisation, she said, showed he must have been 'perfectly aware' of what it stood for". The BBC report also noted that a spokesman said that Kamprad "had long admitted flirting with fascism, but that now, 'there are no Nazi-sympathising thoughts in Ingvar's head whatsoever'".

In June 2013, Kamprad resigned from the board of Inter IKEA Holding SA and his youngest son Mathias Kamprad replaced Per Ludvigsson as the chairman of the holding company. Following his decision to step down, the then-87-year-old founder explained, "I see this as a good time for me to leave the board of Inter IKEA Group. By that we are also taking another step in the generation shift that has been ongoing for some years." Mathias and his two older brothers, who also have leadership roles at IKEA, work on the corporation's overall vision and long-term strategy.

The surname Kamprad was a variant of "Comrade" and dates back to the 14th century; in the 19th century the Kamprad family had become wealthy estate owners in Thuringia. Achim Kamprad's mother was a cousin of Paul Von Hindenburg. Achim was the younger son of an estate owner and had bought the farm Elmtaryd (presently standardized Älmtaryd) near the small village of Agunnaryd (now part of Ljungby Municipality) in the province of Småland; with 449 hectares of land it was the largest farm in the area. He committed suicide a few years after Frans Feodor was born, leaving the farm to Franzisca and with time Franz Feodor. Ingvar Kamprad lived on the farm with his parents, sister and grandmother from the age of 6.

Kamprad died in his sleep of pneumonia at his home in Småland, Sweden, on 27 January 2018 at the age of 91. According to his testament half of Kamprad's inheritance will go to projects in Norrland, a sparsely populated part of Sweden. Kamprad reportedly wanted to develop Norrland and make it possible for young people to live there.
