	Augustus De Morgan - Wikipedia, the free encyclopedia
		De Morgan was interested in the work of both, and corresponded with both; but the correspondence with the Scotsman ended in a public controversy, whereas that with the Irishman was marked by friendship and terminated only by death.
		De Morgan admits that there is one exception; but an exception proves the rule, not in the usual but illogical sense of establishing it, but in the old and logical sense of testing its validity.
		However, De Morgan soon perceived that Hamilton's quantification was of a different character; that it meant for example, substituting the two forms The whole of A is the whole of B, and The whole of A is a part of B for the Aristotelian form All A's are B's.

	DE MORGAN - LoveToKnow Article on DE MORGAN (Site not responding. Last check: 2007-10-18)
		De Morgans writings, however excellent, give little idea of the perspicuity and elegance of his viva voce expositions, which never failed to fix the attention of all who were worthy of hearing him.
		De Morgans other principal mathematical works were The Elements of Algebra (1835), a valuable but somewhat dry elementary treatise; the Essay on Probcfbilities (5838), forming the io7th volume of Lardners Cyclopaedia, which forms a valuable introduction to the subject; and The Elements of Trigonometry and Trigonometrical Analysis, preliminary to the Differential Calculus (5837).
		In 1860 De Morgan endeavoured to render their contents better known by publishing a Syllabus of a Proposed System of Logic, from which may be obtained a good idea of his symbolic system, but the more readable and interesting discussions contained in the memoirs are of necessity omitted.

	About William De Morgan
		In 1859 De Morgan was admitted to the Royal Academy Schools and studied alongside Frederick Walker and Simeon Solomon, who remarked on this "entirely uncommonplace young man; tall, thin, high forehead, aquiline nose and high squeaky voice" - which earned him the nickname "Mouse".
		De Morgan, alongside his partner, the architect Halsey Ricardo, continued work until 1907 but with dwindling success and ill health, he spent much of the year in Florence, Italy with his wife.
		There were many other sides to De Morgan's talents; he designed and made pottery kilns and equipment; sketched ideas for grinding mills and sieves to be used in his workshops; was a knowledgeable chemist; worked on a new gearing system for bicycles; developed telegraph codes and evolved his own system of accounts.

	Toward a Unified Style: William De Morgan and his Increasing Control of Ceramic Production (Site not responding. Last check: 2007-10-18)
		Despite this degree of removal from the actually physical creation of his ceramics, De Morgan's involvement at each stage of the process was nonetheless critical, particularly during kiln firings, since he was the only worker in his factory with the requisite chemical knowledge, and he kept his methods for this process to himself.
		Though De Morgan focuses on just two shades of yellow and one green without any blues, the shades of the flowers and leaves nonetheless are the same yellows and greens that he used in his more overtly Persian style pieces.
		De Morgan occasionally departed from his standard figureless motifs, but in some of these instances, the human forms take on many of the same qualities as the flowers in his images of nature.

	An eye for method: Augustus De Morgan and mathematical education
		Augustus De Morgan was born in 1806 in Madura to a colonel in the Indian Army, who brought his family back to England within months of the child’s birth.
		De Morgan confined his involvement in societies to two organisations: the Society for the Diffusion of Useful Knowledge (SDUK), which gave him his main venue for educational writing; and the Royal Astronomical Society, of which he was secretary for a time and for whom he wrote several historical articles.
		De Morgan’s book is a quite important source for this change in Britain, in what amounted to a second reform of the calculus; but it proceeded much more gradually than had the putsch of the Analytical Society.

	William De Morgan: An Introduction (Site not responding. Last check: 2007-10-18)
		De Morgan was particularly drawn to Eastern tiles.
		It is apparent that De Morgan was very familiar with Eastern design, color, and pottery techniques prior to the Arab Hall project, although his proximity to Leighton's collection undoubtedly refined this knowledge.
		De Morgan, rejecting this stultifying repetition, experimented until he found a means of duplicating a pattern while maintaining the individuality of each tile.

	[Augustus De Morgan]
		Professor De Morgan was born at Madura, in Southern India, in June, 1806, of a family distinguished in the military service.
		It would be premature to try to say what the final judgment of De Morgan's system will be, but it may at least be confidently predicted that the logic of relatives, which he was the first to investigate extensively, will eventually be recognized as a part of logic.
		De Morgan was a deep student of the history of the sciences to which he was devoted.

		De Morgan was prolific and wrote such mathematical texts as Elements of Arithmetic (1830), Penny Cyclopedia (1838) where he coined the term 'mathematical induction', Trigonometry and Double Algebra (1849), a geometric interpretation of complex numbers, and Formal Logic (1847), one of his most important works.
		De Morgan was an uncompromising advocate of religious liberty and free expression; while at Trinity College he would not sign required theological forms and was therefore not allowed to continue with his graduate eduation and fellowship.
