“He might ask you … whether you think a computer could ever enjoy strawberries and cream or could make you fall in love with it.”
It is to Alan Turing — godfather of the digital universe, voracious reader, tragic hero of his era’s inhumane bigotry — that we owe an enormous amount of today’s givens, including my writing this very sentence and your reading it. In Turing: Pioneer of the Information Age (public library), philosophy professor and Turing Archive for the History of Computing director B. Jack Copeland turns to conversations and correspondence with some of Turing’s closest friends and collaborators to explore the life and legacy of this man of uncommon genius with unprecedented depth and insight.
Copeland succinctly captures the magnitude of Turing’s contribution to contemporary life:
To Turing we owe the brilliant innovation of storing applications, and all the other programs necessary for computers to do our bidding, inside the computer’s memory, ready to be opened when we wish. We take for granted that we use the same slab hardware to shop, manage our finances, type our memoirs, play our favorite music and videos, and send instant messages across the street or around the world. Like many great ideas, this one now seems as obvious as the wheel and the arch, but with this single invention — the stored-program universal computer — Turing changed the way we live.

Indeed, it took an exceptional mind — one inhabiting the outermost fringes of the obvious, in every imaginable way — to conceive of such world-changing technology. Copeland goes on to paint a portrait of Turing more dimensional and moving than ever before:
He was a Spartan in all things, inner and outer, and had no time for pleasing decor, soft furnishings, superfluous embellishment, or unnecessary words. To him what mattered was the truth. Everything else was mere froth.
What would it have been like to meet him? Turing was tallish (5 feet 10 inches) and broadly built. He looked strong and fit. You might have mistaken his age, as he always seemed younger than he was. He was good-looking but strange. If you came across him at a party, you would certainly notice him. In fact, you might ask, ‘Who on earth is that?’ It wasn’t just his shabby clothes or dirty fingernails. It was the whole package. Part of it was the unusual noise he made. This has often been described as a stammer, but it wasn’t. It was his way of preventing people from interrupting him, while he thought out what he was trying to say. ‘Ah… Ah… Ah… Ah… Ah.’ He did it loudly.
If you crossed the room to talk to him, you would have probably found him gauche and rather reserved. He was decidedly lah-di-dah, but the reserve wasn’t standoffishness. He was shy, a man of few words. Polite small talk did not come easily to him. He might — if you were lucky — smile engagingly, his blue eyes twinkling, and come out with something quirky that would make you laugh. If conversation developed, you’d probably find him vivid and funny. He might ask you, in his rather high-pitched voice, whether you think a computer could ever enjoy strawberries and cream or could make you fall in love with it.
Like everyone else, Turing craved affection and company, but he never seemed to quite fit in anywhere. He was bothered by his own social strangeness — although, like his hair, it was a force of nature he could do little about. Occasionally he could be very rude. If he thought that someone wasn’t listening to him with sufficient attention, he would simply walk away. Turing was the sort of man who, usually unintentionally, ruffled people’s feathers — especially pompous people, people in authority, and scientific poseurs. … Beneath the cranky, craggy, irreverent exterior there was an unworldly innocence, though, as well as sensitivity and modesty.
Turing: Pioneer of the Information Age goes on to trace the making of an extraordinary mind and extraordinary life, from the invention of the Universal Turing Machine — the granddaddy of the modern stored program computer — to Turing’s codebreaking feats during WWII to the tragic and mysterious circumstances of his death.
