Ada Lovelace, Lord Byron's only legitimate daughter, was rediscovered in the 1930s by pioneers such as Alan Turing, who invented the world's first computer. Four decades on, Ada, a widely-used scientific computer programme, would be named after her. A Female Genius tells the remarkable story of her life, how she overcame the obstacles in her way; her background, her over-bearing mother, her ill health and being a woman in the male-dominated 19th century. It also tells the story how the computer age could have started almost two centuries ago, in 1840s London. Ada Lovelace was the only one who understood this, despite opposition that the principles of science were 'beyond the strength of a woman's physical power of application'. She, for example, wrote the world's first computer programme and foresaw that computers could create music. There are still some who believe she is 'overrated' - the reason why James Essinger researched this book.
