Dr Hayaatun Sillem, CBE

Dr Hayaatun Sillem says the value of education and the self-coaching mindset her parents instilled in her as she grew up in west London has been a guiding principle all her life. The desire to make a positive contribution to society has been another key goal.

 Both are values she is pursuing at the Royal Academy of Engineering, where she has been Chief Executive since 2018, leading a team of some 140 staff, and overseeing a budget of more than £50m.

In 2019, the Financial Times named Dr Sillem the 4th most influential woman in UK engineering, and this year Computer Weekly ranked her the 7th most influential woman in tech.

But with a mixed race background, and parents of modest means, her proudest achievement is having stuck with an internal voice of doubt and a sense of differentness. She is a leading voice on diversity and inclusion in and beyond engineering, and co-chaired the Hamilton Commission on improving representation of black people in UK motorsport with Sir Lewis Hamilton.

There is a “massive diversity deficit in engineering,” she says “And this really matters because engineering and technology are everywhere in our lives. The people who develop deliver, maintain and upgrade the products and services we all rely on every day are currently way too unrepresentative of the society they serve. And that is not good for us as a profession.” It is a balance she is striving to redress.

David Southward

David Southward was a co-founder of Cambridge Consultants in 1960 as a fresh graduate from Cambridge: the foundation of CC is considered to be the start of the Cambridge Phenomenon. The first digital computer he saw after working on analogue computers was a Digital Equipment PDP/11. He went on to become technical director of Sinclair Research working closely with Sir Clive Sinclair. There he helped design the screen for Sinclair’s miniature tv, a storage device for the Sinclair microcomputers and a printer for them.

Geoff Squire OBE

Geoff Squire OBE spent 50 years in the UK IT industry, from machine code to $Bn companies.  Geoff learnt arithmetic and the value of pounds, shillings and pence at an early age doing sums upside down over his father’s shoulder.  University was never an option but interest in numbers led on to jobs in programming and thence to growing roles in ICL.

He is perhaps most famous for establishing Oracle in the UK with an opportunistic pitch to Larry Ellison.  Subsequently Geoff led Veritas to a Y2K $75Bn market cap.  In recent years Geoff has focused, with his wife Fiona, on their grant giving charity and he serves as Chairman of Give as You Live Ltd, a technology company dedicated to raising money for UK charities.
