James Dyson Net Worth: From Art School to Engineering to Dyson’s Personal Life

James Dyson was born on May 2, 1947, in Cromer, Norfolk to Janet and Alec William Dyson. He has two siblings and is named after his grandfather.

As a child, James Dyson studied at an independent boarding school in Holt, Norfolk, called Gresham’s School for about 10 years. During this time, his father died of prostate cancer.

In 1965, after leaving the boarding school, he spent a year studying at Byam Shaw School of Art. He then enrolled in the Royal College of Art (RCA) to study furniture and interior design but eventually decided on engineering, so he made the switch from fine art to industrial design at the same college. His mentor and tutor at the time was the world-renowned structural engineer Anthony Hunt.

In 1968, Sir James Dyson married Deirdre Hindmarsh. The couple has two sons and a daughter.

James Dyson Net Worth: Founding and Expanding the Dyson Empire

James Dyson didn’t invent the vacuums that bear his name straight out of college. He started inventing while still at the Royal College of Art. Let’s see how his story took him to the breakthrough invention and success of the bagless vacuum cleaner.

Early Inventions Before the Dyson Vacuum Cleaners

While still at the RCA, Dyson helped design the Rotork Sea Truck in 1970. The Sea Truck was a high-speed fiberglass, flat-hulled watercraft.

His first individual creation was the Ballbarrow, a modified version of a wheelbarrow that uses a ball instead of a wheel. The Ballbarrow was featured on BBC’s Tomorrow’s World TV program.

After the success of his first invention, Dyson expanded on his idea by inventing the Trolleyball, used to launch boats, as well as the Wheelboat, which could travel on both water and land at up to 40 miles per hour.

The Beginnings of the Dyson Empire

Frustrated by his family’s traditional vacuum, a Hoover that kept getting dust-clogged, James Dyson devised his idea to use cyclonic separation in vacuum cleaners. His idea was to create a vacuum that wouldn’t lose suction when it sucks up dirt. He got the idea from a sawmill that used cyclone technology.

It took Dyson five years and 5,127 different prototypes to launch his G-Force Dyson dual cyclone cleaner in 1983. Unlike traditional vacuum cleaners that used filters and bags to trap dust, the G-Force cleaner used centrifugal force to separate the particles from the air, picking up more debris and making for a more hygienic home.

“I made 5,127 prototypes of my vacuum before I got it right. There were 5,126 failures. But I learned from each one. That’s how I came up with a solution. So I don’t mind failure,” – responded Dyson when interviewed by Fast Company.

I’ve always thought that schoolchildren should be marked by the number of failures they’ve had. The child who tries strange things and experiences lots of failures to get there is probably more creative

However, his product was nothing like others on the market, so UK distributors and manufacturers were hesitant about picking it up. After all, the G-Force cleaner posed a huge threat to the market for replacement dust bags.

Eventually, Dyson managed to release the Dyson dual cyclone cleaner outside his country, in Japan, where his cleaner won the 1991 International Design Fair Prize. The first Dyson product was manufactured in bright pink and sold for around $2,000.

Following his foray into the cleaning world, James Dyson founded his own manufacturing company, Dyson Limited, followed by the foundation of a factory and a research center in Malmesbury, Wiltshire.

The Success of Dyson Cleaners

Dyson started selling his invention with a famous slogan “Say goodbye to the bag”. This, in combination with the quality product, proved very attractive to buyers, so the Dyson Dual Cyclone soon became the fastest-selling vacuum cleaner ever made in the UK.

Dyson licensed the technology in North America to Fantom Technologies between 1986 and 2001. Fast forward to 2005, and the Dyson cleaners were market leaders in the US by value.

As could be expected, such a big success prompted other manufacturers to market their own cleaners that use cyclonic separation. In 1999, Dyson decided to sue Hoover for patent infringement, and the High Court ruled in his favor, stating that Hoover deliberately copied a key part of the Dyson patented designs to make its Triple Vortex bagless vacuum cleaner. The company had to pay the Dyson brand damages of £4 million or around $6.08 million at the time.

In 2014, the inventor came up with an upgraded version of the initial Dyson vacuum cleaner, the 360 Eye robotic vacuum cleaner that scans and maps for navigation and has a custom-designed digital motor for high suction. The product cost over $1,000. Dyson quickly became well known as the best but also the most expensive vacuum cleaner brand.

Expanding the Dyson Brand

Sir James Dyson and his business have come up with some amazing – and some less popular – inventions over the years.

ContraRotator

In 2000, after tremendous success with vacuums, James Dyson decided to expand his business portfolio to include other inventions, too. The first one was the washing machine ContraRotator. These washing machines had two rotating drums that moved in opposite directions. Unlike other machines at the time, the ContraRotator was decorated in bright colors characteristic of the Dyson brand.

The washing machines weren’t a major success and were costly to manufacture, so the brand had to discontinue them in 2005, after a few versions.

Dyson Airblade

A year after the discontinuation of the washing machines, in 2006, Dyson found that the optical illusions as depicted in the lithographs of M.C. Escher, a Dutch artist, were depicted in the water sculpture of engineer Derek Phillips. He was inspired by the Wrong Garden sculpture to invent a new technology to add to his product portfolio – the Dyson Airblade.

He launched the Dyson Airblade in 2006 as the first hand dryer that used a thin sheet of moving air like a squeegee to remove water. Other dryers at the time used heat to evaporate it instead, which took longer and used more energy.

The idea has been tremendously successful and is now offering a hygienic alternative to traditional paper towels and hand dryers in many public restrooms.

Dyson Air Multiplier

In October 2009, Dyson launched the strangest fan you have ever seen. It functions entirely without external blades offering air purifying, humidifying, and heating functions. They called it the Air Multiplier.

Dyson Supersonic

In 2016, the company launched the Dyson Supersonic hair dryer, which uses a smaller motor in the handle that provides better balance and is quieter than most similar products. The innovative Dyson Supersonic hair dryer has reinvented the way people style their hair and has become a top-selling product worldwide.

Sir James Dyson’s Earnings from the Dyson Group

The Dyson Group, Dyson Farming – which we will cover in a moment – and an insurance business called Alpinia, are all housed within the parent company Weybourne Group. Weybourne Group is the Dyson family holding company, and it is responsible for managing Sir James Dyson’s wealth.  Naturally, James Dyson is a majority stakeholder in the group, which also manages his philanthropic organization called the James Dyson Foundation.

The Dyson Holdings revenues jumped from £6 billion to £6.5 billion ($8.22 billion to $8 billion – discrepancy due to historic exchange rate fluctuations) between 2021 and 2022. While we don’t know the exact stake Sir James Dyson owns in the business, it was reported that, in 2022, he landed a whopping 10-figure dividend from his technology company, taking the total amount transferred since the creation of the firm to about $7.7 billion.

Further, Dyson was predicted to receive $600 million or more in 2020 through a further dividend, which wasn’t publicly confirmed.

Philanthropy and Contributions to Education: The James Dyson Foundation and Institute

In 2002, Dyson set up the James Dyson Foundation to support design and engineering education. The charity now operates in the UK, Japan, and the US, to inspire young people to pursue engineering education.

In May 2014, the foundation announced an £8 million donation ($13.18 million at the time) for the development of a technology hub at the University of Cambridge, which would also fund the construction of a development lab for undergraduate engineering students.

The following year, his charity donated £12 million ($18.36 million at the time) for the purchase of a Post Office building for Imperial College London. The college was to open the Dyson School of Design Engineering in the building, where it would teach a Master’s degree that lasts four years.

In 2021, the Dyson Foundation invested £4 million ($5.48 million at the time) toward the construction of a £50 million ($68.5 million at the time) location for cancer services at the Royal United Hospital, which will be called the Dyson Cancer Center. The same hospital also opened a Dyson Center for Neonatal Care ten years before using a £500,000 donation from the charity.

Finally, the foundation provides the James Dyson Award to young designers to inspire the next generations to study and be innovative.

This is not the only charity Sir James Dyson is involved in. He is also a trustee of a separate charity with his wife called The James and Deirdre Dyson Trust, which is used to make personal donations to different causes. For instance, in 2019, this charity donated £18.75 million ($23.81 million at the time) to Gresham’s to build a new STEAM Education building.

Between 2011 and 2017, James Dyson served as the Provost of the Royal College of Art. He also opened a new university called the Dyson Institute of Engineering and Technology in 2017.

Property Portfolio and Personal Investments: Dyson’s Wealth Beyond Dyson

In addition to investing in research and development, Dyson has been putting millions into artificial intelligence and robotics research.

To stay at the forefront of technology advancements, the business has allocated millions per week to research and development. His company has invested in everything from solid-state batteries and robotic vacuum cleaners to electric vehicles and medical ventilators. Dyson employs over 3,500 scientists and engineers and is involved in over 40 university research programs.

One example of such investments is Dyson’s £110 million ($150.7 million when founded in 2021) ‘farm of the future‘. The company has one of the largest farming operations in the UK, spread across 35,000 acres in locations like Oxfordshire, Somerset, and Gloucestershire.

Dyson reportedly spent £500 million (around $600 million) on a new type of electric car, but that project has been scrapped. This product would have cost £150,000 ($192,000 at the time) just to break even, not to mention make a profit. He reportedly invested in this from his personal net worth.

Aside from this, we know very little about the businessman’s personal investments except for his publications and assets like real estate, jets, and yachts.

Publications and Authorship

Sir James Dyson has published two autobiographies to date:

  • Against the Odds: An Autobiography in 1997
  • Invention: A Life in 2021

Real Estate

Thanks to his incredible success in innovation, Dyson has accumulated a net worth that allows him to live a luxurious life. That being said, he has invested a fortune in real estate.

In 1999, the inventor acquired Domaine des Rabelles, an estate that also includes a winery, located near Villecroze and Tourtour in France. The family has been producing wine ever since.

In 2003, he spent £15 million ($24.45 million at the time) for a 300-acre Georgian property called Dodington Park in South Gloucestershire. His family also reportedly owns a house in Chelsea, London, though we don’t know its value.

In 2019, Dyson spent over $50 million to buy a triplex flat at the top of Singapore’s tallest building, the Guoco Tower, but he sold this property in 2020 at a loss.

He is also the beneficial owner of a Singapore-based business with 31 UK properties, called Weybourne Holdings. The properties are worth at least £287 million (around $364 million).

Private Jets and Yachts

Dyson’s Nahlin vessel is the largest British-owned super yacht, ranked 36th in a survey of the world’s biggest yachts in 2013. The yacht is worth over $70 million.

In addition to this, Dyson also owns two Gulfstream G650ER private jets and an AgustaWestland AW-139 helicopter. His jet collection is worth over $65 million, while his helicopter is worth between $5 million and $9 million.

What Can We Learn from James Dyson’s Story?

James Dyson, the founder of the famous vacuum cleaners among other products, has a story that should inspire young people (and just about everyone else) to study, innovate, and become entrepreneurs.

His story is one of determination and perseverance. Dyson’s success is a testament to resilience, since not all of his products achieved the same level of success, and he has gone through many controversies and problems over the years.

Although his business has achieved great success, it hasn’t been without challenges. The COVID-19 pandemic, for instance, forced the company to temporarily close its manufacturing facilities, which led to a decrease in production. The microchip shortage has been a major issue, too.

Brexit has been another significant challenge for the family, so when Dyson announced it would move the company’s headquarters to Singapore, people accused him of hypocrisy for supporting Brexit. Dyson’s story teaches us that, in business, embracing failure is vital for success, and it is important to learn from one’s mistakes.

Dyson is known for his innovative approach to product design and engineering, challenging conventional thinking, and using advanced technologies to solve everyday problems. This is what led him to the development of game-changing Dyson products like cleaners, air purifiers, hair styling products, and more. His story underscores the value of innovation and quality – his products are known for their exceptional design – in entrepreneurship.

Finally, his journey to success teaches us about patience. He didn’t achieve greatness overnight. It took him years of research and development, endless tries and failures before he could create something that the world would love.
