David Potter CBE

4 July 1943 - 28 June 2026

David Potter was an IT entrepreneur and tech tycoon, known as the ‘British Bill Gates’ who launched the world’s first mass-produced handheld computer.  He attended Bishops Prep in the Std 1 Class in 1952.  From there he went to Price Edward in Zimbabwe and after a brief stay at UCT he went to Trinity College Cambridge on a Beit Scholarship.

Nicky Bicket (1973F) informed us of the sad passing of David Potter and with the correspondence between the UK Branch and Paul Murray at the ODU who normally writes up the obits, Charles McGregor (1969F) wrote: "I have had the privilege of knowing both David and Elaine, and I served alongside her as a fellow Trustee of the University of Cape Town Trust. They were both extraordinarily generous supporters of the University. And when in CT, I was also fortunate to be able to  entertain them at my home."

Upon further research from the Bishops Archives, we managed to find an insert from an OD in the UK at the time, Nick Winearls (1970W), of an account in the London Sunday Times - about David who was in Standard 1 at Bishops in 1952:

"David left Bishops and attended Prince Edward School in Zimbabwe, then Cambridge, and later the Imperial College, London, where he did a doctorate in theoretical physics. He claims he acquired his business skills in less high-tech jobs as a lorry-driver and ice-cream vendor. He later invested the £100 000 he had made playing the stock market in developing an early home-computer flight-simulator game. The game earned him a fortune and was the break that Potter then 53, needed to get his business off the ground." 

(September 1997 edition of The Diocesan College magazine, p. 89).

David Potter was the Chairman of Psion, the palmtop computer company, which stands for Potter Scientific Instruments Or Nothing.  The company grew into a worldwide conglomerate with offices not only in the UK but in Boston, Amsterdam and Frankfurt distributing to scores of countries around the world.

The following was written by Alan Weller - Saturday July 11 2026, 12.01am, The Times:

"While teaching in California in 1974 David Potter realised that the microchip was going to change the world. At the cusp of that revolution, the South African-born Briton resolved to do no less than “lead the industry, advance society and enrich people’s lives”.

He would arguably go some way to achieving it by founding the British company that would design and make the world’s first handheld personal computer, one of the status symbols of executive achievers in the Nineties.

To go from academic to chief executive of one of Britain’s leading listed tech companies, Potter needed capital, but did not want to borrow. The 1974 stock market crash as a result of the oil crisis gave the man who would become known as the “British Bill Gates” the means to join the revolution.

He invested his £3,000 savings into six companies, including GEC, Rank Xerox and Racal Electronics. When he returned to Britain in 1975 his investments had more than doubled. On a skiing trip to Austria that year he discovered the duvet and decided that in a few years most Britons would be sleeping under one. Potter put all his money into Britain’s only significant duvet maker, based in Lincolnshire, and grew his capital to the point that he was ready to start his own company with £70,000.

He launched Potter Scientific Instruments or Nothing (Psion) during the “Rustbowl” recession in 1980. A restless soul who was tall with angular features, Potter had a simple plan to recruit top boffins from academia — many of whom he had taught at Imperial College London — and write software for the home computers about to proliferate in British homes.

The “game changer” was a flight simulator game that he and his first coder, Charles Davies, devised for Clive Sinclair’s ZX81 as well as Acorn computers. Its success made Psion the largest provider of software for microcomputers by 1982, by which point the company was turning over £1.6 million with a profit of £600,000 and 15 employees.

Potter had not needed to borrow a penny, until he took his begging bowl to the City for the first time to make hardware, or “metal bashing” as disparaging service-economy obsessed City analysts called it. Undeterred, Psion launched “The Organiser”, the world’s first mass-produced handheld personal computer in 1984, which combined the functions of diary, address book, notebook and computer.

For the next 17 years Psion would be at the vanguard of “personal digital assistant” products, or PDAs. Bolstered by the flotation of 60 per cent of the company on the London stock exchange in March 1988, the company launched several iterations that were lighter, had battery life of up to 70 hours, a bigger screen and could handle more data for an ever-growing list of functions and the ability to back up files on to a PC.

The company invested heavily in R&D to design its own chips, enabling the more powerful 16-bit architecture of the Series 3 in 1991. However, the company’s market leadership in PDAs was increasingly under threat. Palm (with its stylus for entering data) was cornering the PDA market in the US, ahead of the Apple Newton MessagePad. Japanese calculator manufacturers such as Sharp and Casio also parked their tanks on Psion’s lawn.

The company was now valued at £300 million and with venture capital available, Potter tried to acquire Alan Sugar’s Amstrad in 1996 because the company’s Dancall subsidiary would have given him the means to develop a mobile phone. Sugar liked him personally because he was not “toffee-nosed” like so many of the City “suits” he had to deal with, but after a fierce round of negotiations they could not agree on a price.

Potter had another option. Frustrated at the City’s aversion to “metal bashing”, he decided to pivot to licensing software. Since the early Nineties Potter had been in discussions with the Finnish telecommunications company Nokia about developing global software for a new generation of mobile phones that would be multi-functional and packed with more data.

In 1998 he helped to put together a consortium of mobile phone producers, taking a year to persuade erstwhile enemies such as Nokia, Ericsson and Motorola to co-develop the Symbian OS operating system that was based on Psion’s EPOC software using British ARM processors. Samsung, Sony and Matsushita later joined. It would become the industry standard for the mobile phone market and enabled multi-tasking, internet browsing and early app ecosystems — greatly influencing the later smartphone software.

Applicable to more than 100 types of phones and installed on some 125 million devices, Symbian generated licensing revenues for Psion of some $120 million a year and would sustain the British tech company well into the new millennium. The Observer noted in a 1998 profile of Potter that the British tech entrepreneur had outflanked US competitors such as Microsoft to provide the software for more than three quarters of the world’s mobile phones, leading to a doubling of the company’s share price.

Potter began to withdraw from the PDA market in 2001, to focus on Symbian OS, but in 2004 Psion sold its Symbian shares to Nokia for £136 million. His competitiveness on a tennis court attested to how much he liked to win, but ultimately he decided he could not compete with the bigger US players and though Symbian remained the world’s most popular smartphone operating system until 2010, it would be superseded by the Google-owned Android smartphone operating system and iOS system used by Apple.

He later blamed the short-term outlook in the City of London and absence of risk-taking culture that would have enabled him to scale up and keep adapting the software. “If I was valued by American venture capitalists it would be worth three times the price,” he said.

David Potter was born into a family of English heritage in the port of East London, South Africa, in 1943 and was brought up in Cape Town, where he attended Bishops school.

His father died when he was a baby and he grew up believing that he didn’t need one. “I almost brought up myself. It gave me a large amount of self-confidence to be able to deal with things,” he said, noting that many entrepreneurs grow up without fathers.

Because his mother, a nurse, went out to work, he was looked after by his grandmother, an early female graduate of Classics who read him Winnie-the-Pooh in Latin as he sat on her knee. He moved to Rhodesia (present-day Zimbabwe) aged ten after his mother remarried, and attended Prince Edward School in Salisbury (now Harare) while founding his first enterprise in the school holidays, a photographic studio.

Aged 19 Potter won a scholarship to read natural sciences at Trinity College, Cambridge. During one holiday, he rented an ice-cream van and parked it outside the gates of Hyde Park. Roaring trade came to an abrupt halt when he was dragged out of the vehicle by a group of more established vendors, taken behind a tree and persuaded — on pain of being beaten up — to put that particular enterprise to an end. He would go on to get a first and then do a PhD in mathematical physics at Imperial College London, staying on to become a lecturer in applied physics.

While exploring chaos theory, climate change, the oceans, the structure of galaxies and plasma physics, he began to use computer simulation. As an early expert on the use of computers in physics he taught at the University of California in 1974-75 and wrote a book on the subject.

By then he had married Elaine Potter, a Sunday Times investigative journalist who worked on the paper’s famous investigation into the thalidomide scandal. They had three sons.

Potter stepped down from his executive role at Psion on health grounds in 1999 but remained chairman. The following year Psion bought the Canadian company Teklogix for £240 million to become Psion Teklogix, focusing on manufacturing business-to-business data-collection hardware. Motorala bought Psion plc in 2012 for $200 million.

Potter enjoyed landscape gardening at his farmhouse in Oxfordshire and at his beach house in Cape Town. He also loved hosting dinners, but guests representing the media, arts and business were expected to sing for their supper and fierce debate was a prerequisite.

The Times reported in 2010 that Potter and his wife were launching the Bureau of Investigative Journalism with £2 million of their own money, because he felt that governments were not being held to account.

Potter built his career on doing just that to those around him. “He’s intellectually enjoyable but intellectually fierce,” said a former colleague. “You can’t go to him with a half-baked idea. Even if you’ve got 90 per cent he spends the whole time demolishing you for the 10 per cent flakiness.”
