5 Things You Didn't Know About Ikea's Billionaire Founder Ingvar Kamprad, the world's eighth richest person, died at 91 on Jan. 27.

Ingvar Kamprad, the founder of DIY affordable (and relationship testing) furniture maker and Swedish food purveyor Ikea, died on Jan. 27 at the age of 91.

Having been in business for more than seven decades and with a significant global presence, any entrepreneur would want to aim for the kind of success that Kamprad achieved with Ikea, one that earned him a fortune worth $58.7 billion. His wealth earned him the status of the world's eighth richest person, according to Bloomberg.

With that in mind, here are five things that you might not know about Kamprad and his approach to business.

He had a customer-first point of view.

Though Kamprad stayed largely out of the media spotlight, rarely giving interviews or personal statements, he did write a document in 1976 that explains the ethos of the company, called The Testament of a Furniture Dealer. Namely, that the goal and guiding force behind the company's decisions would be to put the needs of the user at the forefront. "The many people usually have limited financial resources. It is the many people whom we aim to serve," Kamprad wrote. "The first rule is to maintain an extremely low level of prices. But they must be low prices with a meaning. We must not compromise either functionality or technical quality."

He made the most of his resources.

Kamprad was so concerned with saving money that he was widely nicknamed "Uncle Scrooge" and "The Miser." He owned a Volvo, always flew coach and made sure that when his leadership team traveled for business, they stayed in the least expensive hotels. He eschewed a more corporate look of suits and ties, and if there was an opportunity to recycle something or snag some condiments from a restaurant, he would. While you may not go to Kamprad's extremes -- though he owned some expensive properties, it turns out -- it is important to make the most of the resources you have at your disposal. Because, as he once, wrote, "Time is your most important resource. You can do so much in 10 minutes. Ten minutes, once gone, are gone for good. You can never get them back."

He didn’t settle on one product.

Kamprad started his first business when he was 5 selling matches around his neighborhood, graduating to Christmas ornaments, fish, pencils and seeds. Ikea didn't just always sell furniture. That part of the business started in 1948, but for those first few years, after he launched the mail-order company at 17, he sold items such as nylons, pens and wallets out of a repurposed milk truck. A good reminder that where you begin and where you end up may look very different.

He believed work shouldn’t just be work.

"A job must never be just a livelihood," Kamprad wrote. "If you are not enthusiastic about your job, a third of your life goes to waste." He believed that the Ikea spirit was built on a foundation of enthusiasm and that without it, it was impossible to strive for great things, lead or motivate colleagues.

He wasn’t afraid of taking a wrong turn.

Kamprad was of the school that if you aren't making mistakes, you're not trying hard enough. "Only while sleeping one makes no mistakes. Making mistakes is the privilege of the active -- of those who can correct their mistakes and put them right," he wrote. "Our objectives require us to constantly practice making decisions and taking responsibility, to constantly overcome our fear of making mistakes. The fear of making mistakes is the root of bureaucracy and the enemy of development."
