La famille quitta bientot pour l'Angleterre ou il sera enseigné dans des écoles privées le Latin, le Grècque, l'Hébreu, et les mathématiques. Il détestait les examens. Il entra à Trinity Collège, Cambridge en 1823. Quatre ans plus tard, il refusa de poursuivre ses études n'aimant pas l'aspect compétitif des masters. Refusant l'ambition de ses parents de faire un pretre de lui, Augustus de Morgan, joua d'abord avec l'idée d'étudier la médecine, ensuite la loi. Mais il décida enfin que sa vocation était de devenir mathématicien. Il deviendra premier professeur à UCL (University College London), en 1928. Son temps passé là ne fut pas des plus tranquilles, il résigna de sa poste par principe après qu'un de ses collègues fut jeté dehors sans explication. Il reprit la place 5 ans plus tard lorsque son remplacent mourut. Mais il allait encore abandonner son poste en 1861. En temps que professeur, il avait une réputation de rendre les maths vivantes et intéressant pour ses élèves.

Augustus De Morgan Augustus De Morgan lost the sight of his right eye shortly after birth. At school he did not excel. De Morgan entered Trinity College Cambridge in 1823 at the age of 16. He received his B.A. but a theological test was required for the M.A., something to which De Morgan strongly objected. In 1826, he returned to his home in London and entered Lincoln's Inn to study for the Bar. In 1827, he applied for the chair of mathematics in the newly founded University College in London and, despite having no mathematical publications, he was appointed. He wrote a popular book Elements of arithmetic in 1830. In 1849, he published Trigonometry and double algebra , in which he gave a geometric interpretation of complex numbers. He also wrote a popular calculus book. In 1838, he defined and introduced the term "mathematical induction", putting a process that had been used without clarity on a rigorous basis. He recognized the purely symbolic nature of algebra and he was aware of the existence of algebras other than ordinary algebra. He introduced De Morgan's laws and his greatest contribution is as a reformer of mathematical logic. In 1866, he was a co-founder of the London Mathematical Society and became its first president. In the same year De Morgan was elected a Fellow of the Royal Astronomical Society. De Morgan was never a Fellow of the Royal Society, as he refused to let his name be put forward. He also refused an honorary degree from the University of Edinburgh.

His father was Col. De Morgan, who held various appointments in the service of the East India Company . His mother was descended from James Dodson, who computed a table of anti-logarithms, that is, the numbers corresponding to exact logarithms. It was the time of the Sepoy rebellion in India, and Col. De Morgan removed his family to England when Augustus was seven months old. As his father and grandfather had both been born in India, De Morgan used to say that he was neither English, nor Scottish, nor Irish, but a Briton "unattached," using the technical term applied to an undergraduate of Oxford or Cambridge who is not a member of any one of the Colleges. When De Morgan was ten years old, his father died. Mrs. De Morgan resided at various places in the southwest of England, and her son received his elementary education at various schools of no great account. His mathematical talents were unnoticed till he had reached the age of fourteen. A friend of the family accidentally discovered him making an elaborate drawing of a figure in

10.7. De Morgan, Augustus (1806-1871) IRA Augustus De Morgan was an important innovator in the field of logic. In addition, he had many contributions to the field of mathematics and the chronicling of the history of mathematics. Augustus De Morgan was born in Mandura, India, on June 27, 1806. His father was a colonel in the Indian Army. His family soon moved to England where they lived first at Worcester and then at Taunton. His early education was in private schools where he learned Latin, Greek, Hebrew, mathematics and a dislike of exams. He entered Trinity College, Cambridge, in 1823 and graduated four years later. After graduation, De Morgan reached the point of deciding what to do with the rest of his life. Dubious of competitive fellowships and master degrees, he refused to continue his education. Fearful of hypocrisy and religious bigotry, he also rejected his parents' wish of becoming a priest. After contemplating medicine and law, he finally decided to become a mathematician. In 1828, he was awarded the position of first Professor of Mathematics at University College in London. His time at the university was far from quiet. In 1831, he resigned on principle after another professor was fired without explanation. He regained his job five years later when his replacement died in an accident. He would resign again in 1861. As a teacher, he was highly praised at making mathematics alive and interesting to his students. In addition, he wrote textbooks on numerous subjects in mathematics and logic.

Quotations by Augustus De Morgan It is easier to square the circle than to get round a mathematician. Quoted in H Eves In Mathematical Circles (Boston 1969). Every science that has thriven has thriven upon its own symbols: logic, the only science which is admitted to have made no improvements in century after century, is the only one which has grown no symbols. Transactions Cambridge Philosophical Society , vol. X, 1864, p. 184. [When asked about his age.] I was x years old in the year x . In H. Eves In Mathematical Circles, Boston: Prindle, Weber and Schmidt, 1969. The moving power of mathematical invention is not reasoning but imagination. The imaginary expression a ) and the negative expression - b , have this resemblance, that either of them occurring as the solution of a problem indicates some inconsistency or absurdity. As far as real meaning is concerned, both are imaginary, since - a is as inconceivable as a Said in 1831 Imagine a person with a gift of ridicule [He might say] First that a negative quantity has no logarithm; secondly that a negative quantity has no square root; thirdly that the first non-existent is to the second as the circumference of a circle is to the diameter. I don't quite hear what you say, but I beg to differ entirely with you.

Combining Probability and Logic 4th Augustus de Morgan Workshop King's College London 4th - 6th November 2002 How is probability related to logic? Should probability and logic be combined? If so, how? Bayesianism tells us we ought to reason probabilistically. In that sense, probability theory is logic. How then does probability theory relate to classical logic and the various non-classical logics that also stake a claim on normative reasoning? Is probability theory to be preferred over other logics or vice versa? Is probability theory to be used in some situations, and the other logics in other situations? Or should probability be combined with other logics? These questions were important in the time of Augustus de Morgan. Indeed de Morgan himself argued that Aristotelian logic was unnecessarily restrictive in scope, and with his contemporary George Boole he began to broaden its horizons, initiating a rennaissance in logic. The title of his most important book bears witness to his vision of a comprehensive logic encompassing probability: "Formal Logic; or the calculus of Inference, Necessary, and Probable". While the above questions are not new, we now urgently require some answers. Artificial intelligence is one key discipline in which probability theory competes with other logics for application. It is becoming vitally important to evaluate and integrate systems that are based on very different approaches to reasoning, and there is strong demand for theoretical understanding of the relationships between these approaches.
