Empire of the Sum by Keith Houston (2023 W. W. Norton & Company hardcover 374pp)
Empire of the Sum is a 300+ page book about the history of the calculator. That fact may put you off from reading it immediately but I urge you to reconsider if you have any interest in technology, innovation, invention and stories of the little-known giants whose shoulders we all stand upon.
I don’t know if it’s a stipulation of his contract but all three of Keith Huston’s books to date have been exquisite little hardbacks – well designed and illustrated and obviously produced by a publisher who puts in the maximum effort. Shady Characters (2013) looked at the history and use of unusual typographic characters while The Book (2016) followed the long and often surprising history of the book as a physical object.
Empire of the Sum is divided up into 15 main chapters, each centered around one of the ‘greatest hits’ of calculating machine history. It starts with the human hand itself and goes through to the invention of computer spreadsheet programs. At first, I was unhappy at this arrangement as I felt this would skip many intermediate steps but upon reading further, I was happy to discover the author often loops back within each chapter to describe other developments and puts the device in question into its proper context. Many of the lessor-known thinkers and inventors from history are also given due credit for their part in the general advancement of calculator and eventually computing technology.
In other hands this could be a total bore-fest but Houston is a skillful and engaging writer. His frequent use of humour and historical anecdotes brings the narrative to life.
The rapid rise of discrete calculating machines in the late 20th century and their apparent fall in the early 21st is a fascinating story in itself. The world is now full of unused old calculators stuffed into cupboards and drawers as their function has largely been absorbed into computers and their recent offspring the smartphone. I'm not sure how I feel about events that took place essentially during my lifetime now being part of a historical study.
I enjoyed the tale Houston had to tell, it might be a little too niche for many readers but it is well worth your time to dip into and perhaps learn more about how we got to our current technological situation.
