### About the author

This book, aimed at the general reader and now available again, is the first full-length biography of George Boole (1815–1864) who has been variously described as the founder of pure mathematics, one of the fathers of computer science and discoverer of symbolic logic. Boole is mostly remembered as a mathematician and logician whose work found application in computer science long after his death, but this biography reveals Boole as much more than a mathematical genius; he was a child prodigy, self-taught linguist and practical scientist, turbulent academic and devoted teacher, social reformer and poet, psychologist and humanitarian, religious thinker and good family man – truly a nineteenth-century polymath.

" He was a brilliant thinker, the possessor of a truly original mind. His story is

ourstory: the creation of one of the great intellectual pillars that support our modern world. It is the story of a remarkable man, beautifully told."Ian Stewart, Emeritus Professor of Mathematics, at the University of Warwick, England, and popular-science and science-fiction writer

George Boole was born in Lincoln, England, the son of a struggling shoemaker. Boole was forced to leave school at the age of sixteen and never attended a university. He taught himself languages, natural philosophy and mathematics. After his father’s business failed he supported the entire family by becoming an assistant teacher, eventually opening his own boarding school in Lincoln. He began to produce original mathematical research and, in 1844, he was awarded the first gold medal for mathematics by the Royal Society.

Boole was deeply interested in the idea of expressing the workings of the human mind in symbolic form, and his two books on this subject, *The Mathematical Analysis of Logic* (1847) and *An Investigation of the Laws of Thought* (1854) form the basis of today’s computer science and electronic circuitry. He also made important contributions to areas of mathematics such as invariant theory (of which he was the founder), differential and difference equations and probability. Much of the ‘new mathematics’ now studied by children in school – set theory, binary numbers and Boolean algebra, has its origins in Boole’s work.

In 1849, Boole was appointed first professor of mathematics in Ireland’s new Queen’s College (now University College) Cork and taught and worked there until his tragic and premature death in 1864. In 1855, he had married Mary Everest, a niece of the man after whom the world’s highest mountain is named. The Booles had five remarkable daughters including Alicia, a mathematician, Lucy, a professor of chemistry, and Ethel (Voynich), a novelist and author of *The Gadfly.*

“MacHale has had a splendid tale to tell, and has met the challenge exceedingly well; his book deserves to become widely read.”

Times Higher Education Supplement.“This is a well-researched and well-written biography of one of the most important figures in the history of logic, and perhaps also in the history of mathematics

per se.”Mathematical Review“MacHale’s biography is indeed an attractive form of historical reading, and I certainly enjoyed some self-education in the process.”

Irish Times

“(MacHale) gives us a taste of what it might be like to be a genius struggling to understand and to express insights.”

Desmond MacHale is Emeritus Professor of Mathematics at University College Cork, where Boole was the first Professor of Mathematics.
