Childhood
George Buhl was born and raised in the family of the ill-fated artisan John Bull, who was keen on science. Father, interested in mathematics and logic, gave his first lessons to his son, but he was unable to discover early his outstanding talents in the exact sciences, and his first passion was the classical authors.Only at the age of seventeen, Buhl reached higher mathematics, moving slowly because of a lack of effective assistance. -

Other works
Although, with the exception of mathematical and logical works, Bul was published little, his writings reveal a wide and deep acquaintance with literature. His favorite poet was Dante, with "Paradise" he liked more than "Hell".
Constant subjects of study were for Buhl the metaphysics of Aristotle, the ethics of Spinoza, the philosophical writings of Cicero and many such works -

Career
In 1834 he opened his school in Lincoln In 1839 he presented several works, among which were "Theory of Mathematical Transformations" for the "Cambridge Mathematical Journal.
In 1849 he became the first professor of mathematics at King's College in Cork, Ireland. In 1854, he was engaged in algebra and logic, and his writings in this area are better known as Boolean algebra. In the same year he introduced the concept of a symbolic method of logical inference in the publication "Laws of Thought" -

Greyfriars
Boole participated in the Mechanics Institute, in the Greyfriars, Lincoln, which was founded in 1833. Edward Bromhead, who knew John Boole through the institution, helped George Boole with mathematics books and he was given the calculus text of Sylvestre François Lacroix by the Rev. George Stevens Dickson of St Swithin's, Lincoln. Without a teacher, it took him many years to master calculus. -

Lincoln Topographical Society
At age 19, Boole successfully established his own school in Lincoln. Four years later he took over Hall's Academy in Waddington, outside Lincoln, following the death of Robert Hall. In 1840 he moved back to Lincoln, where he ran a boarding school. Boole immediately became involved in the Lincoln Topographical Society, serving as a member of the committee, and presenting a paper entitled. -

Building society
Boole became a prominent local figure, an admirer of John Kaye, the bishop.He took part in the local campaign for early closing. With E. R. Larken and others he set up a building society in 1847. He associated also with the Chartist Thomas Cooper, whose wife was a relation. -

Boolean algebra
The Boolean algebra is named after the great English mathematician George Boole .The logic algebra is a branch of mathematics that studies statements viewed from their logical values (truth or falsity) and logical operations on them. rules are established for performance of logic operations:The first operations are performed in parentheses, then in the following order: inversion (negation ¬), conjunction (ʌ), disjunction (v), implication (→), the equivalent (=). -

Personal life and heritage
In 1855, he married the daughter of the Greek professor Mary Everest, who helped Buly work and left interesting memories of her husband after his death. Of their five daughters, three were outstanding personalities. The eldest, Lucy, became a professor of chemistry, the middle one, Alice, received a number of interesting results in geometry. But the most famous was the youngest daughter - Ethel Lillian, in the marriage Voynich, who wrote several novels, including "Gadfly". -

Memory
In honor of George Buhl in 1964 called the crater on the moon.
In his honor, the type of the Boolean variable in programming was called.
In 2015, the Irish National University in Cork celebrates 200 years since the birth of George Buhl.
