Naomi Alderman returns with her series that explores the minds of the greatest thinkers in history. From political theorists to scientists to inventors, authors and artists. Our world is based on their ideas and innovations. How did they do their work, what did they struggle with, where did they find their dedication, creativity and inspiration?

A highly skilled engineer, Isambard Kingdom Brunel was driven by a desire to be the best, to achieve perfection in everything he built. From the Clifton Suspension Bridge to Paddington Station, Brunel’s work left indelible stamps on Britain. Unconcerned with cost and willing to put himself and his workers at risk to achieve his goals, his need for perfection perhaps went too far, by today’s standards. He had a vision for a future that, in his own time, seemed impossible: one where people could travel by smooth, comfortable, fast railways.

Special thanks to Tim Bryan Brunel curator at the SS Great Britain in Bristol.
