<person> 1815-11-02 - 2008-05-11 22:58 best known for his contribution to symbolic logic ({Boolean Algebra}) but also active in other fields such as probability theory, algebra, analysis, and differential equations. He lived, taught, and is buried in Cork City, Ireland. The Boole library at University College Cork is named after him. For centuries philosophers have studied logic, which is orderly and precise reasoning. George Boole argued in 1847 that logic should be allied with mathematics rather than with philosophy. Demonstrating logical principles with mathematical symbols instead of words, he founded symbolic logic, a field of mathematical/philosophical study. In the new discipline he developed, known as Boolean algebra, all objects are divided into separate classes, each with a given property; each class may be described in terms of the presence or absence of the same property. An electrical circuit, for example, is either on or off. Boolean algebra has been applied in the design of binary computer circuits and telephone switching equipment. These devices make use of Boole's two-valued (presence or absence of a property) system. Born in Lincoln, Lincolnshire, UK, George Boole was the son of a tradesman and was largely self-taught. He began teaching at the age of 16 to help support his family. In his spare time he read mathematical journals and soon began to write articles for them. By the age of 29, Boole had received a gold medal for his work from the British Royal Society. His 'Mathematical Analysis of Logic', a pamphlet published in 1847, contained his first statement of the principles of symbolic logic. Two years later he was appointed professor of mathematics at Queen's College in Ireland, even though he had never studied at a university. He died in Ballintemple, Ireland, on 1864-12-08. {Compton's Encyclopedia Online (http://comptons2.aol.com/encyclopedia/ARTICLES/00619_A.html)}. (1998-11-19)

Mary Everest Boole (11 March 1832 in Wickwar, Gloucestershire – 17 May 1916 in Middlesex, England) was a self-taught mathematician who is best known as an author of didactic works on mathematics, such as Philosophy and Fun of Algebra, and as the wife of fellow mathematician George Boole. Her progressive ideas on education, as expounded in The Preparation of the Child for Science, included encouraging children to explore mathematics through playful activities such as curve stitching.

George Boole

George Boole (; 2 November 1815 – 8 December 1864) was a largely self-taught English mathematician, philosopher, and logician, most of whose short career was spent as the first professor of mathematics at Queen's College, Cork in Ireland. He worked in the fields of differential equations and algebraic logic, and is best known as the author of The Laws of Thought (1854) which contains Boolean algebra. Boolean logic is credited with laying the foundations for the Information Age.

Boole was the son of a shoemaker. He received a primary school education and learned Latin and modern languages through various means. At 16, he began teaching to support his family. He established his own school at 19 and later ran a boarding school in Lincoln. Boole was an active member of local societies and collaborated with fellow mathematicians.

In 1849, Boole was appointed the first professor of mathematics at Queen's College, Cork (now University College Cork) in Ireland, where he met his future wife, Mary Everest. He continued his involvement in social causes and maintained connections with Lincoln. In 1864, Boole passed away due to fever-induced pleural effusion after developing pneumonia.

Boole published around 50 articles and several separate publications in his lifetime. Some of his key works include a paper on early invariant theory and "The Mathematical Analysis of Logic," which introduced symbolic logic. Boole also wrote two systematic treatises: "Treatise on Differential Equations" and "Treatise on the Calculus of Finite Differences." He contributed to the theory of linear differential equations and the study of the sum of residues of a rational function. In 1847, Boole developed Boolean algebra, a fundamental concept in binary logic, which laid the groundwork for the algebra of logic tradition. Boole also attempted to discover a general method in probabilities, focusing on determining the consequent probability of events logically connected to given probabilities. Boole developed Boolean algebra, which forms the foundation of digital circuit design and modern computer science. His work was expanded upon by various scholars, such as Charles Sanders Peirce and William Stanley Jevons. Boole's ideas later gained practical applications when Claude Shannon and Victor Shestakov employed Boolean algebra to optimize the design of electromechanical relay systems, leading to the development of modern electronic digital computers. University College Cork celebrated the 200th anniversary of Boole's birth in 2015, highlighting his significant impact on the digital age.

Boole's contributions to mathematics earned him various honors, including the Royal Society's first gold prize for mathematics, the Keith Medal, and honorary degrees from the Universities of Dublin and Oxford.
