The origin story of one of the most influential and transformative business leaders and philanthropists of the modern age.

Bill Gates is one of the most transformative figures of our age. In Source Code he takes us back to his beginnings. He describes with candour his childhood in Seattle, the centrality of family - his close relationship with his card-playing grandmother and his demanding but caring parents - his struggles to fit in, his rebelliousness, his first deep friendships and the impact of losing his closest friend.

We see Gates's extraordinary mind developing, the restless teenager who discovered a love of coding and computing at the dawn of a new era and felt that 'by applying my brain, I could solve even the world's most complex mysteries'. We see the earliest signs of his phenomenal business acumen, which led him to drop out of Harvard at the age of 20 to devote all his energies to Microsoft, the company he started with his childhood friend Paul Allen. He writes about his first encounters with three Steves - Jobs, Wozniak and Ballmer - who would play a crucial role in so much that followed.

The book ends in the late 1970s when Microsoft, still with only a dozen employees, signed its first deal with Apple. The deals would go on and Microsoft would grow unimaginably. Yet Gates never forgot his mother's reminder that he was merely a steward of any wealth that he gained. This warm and inspiring book, Bill Gates' origin story, allows readers to understand his energy and ambition - and to see how he sets himself in the world.
