George Peacock was an English mathematician and a priest. He was born on April 9, 1791, and passed away on November 8, 1858. He is well-known for helping to change how mathematics was taught at Cambridge University. He also played a big part in developing what is now called the British algebra of logic.

Early Life and Education
George Peacock was born on April 9, 1791, in Thornton Hall, Denton, England. His father, Thomas Peacock, was a priest and also ran a school. George first learned from his father. Later, he attended Sedbergh School and Richmond School. At Richmond, he was very good at both classic subjects and the basic math needed for college.
In 1809, George Peacock became a student at Trinity College, Cambridge. He finished his studies in 1812, ranking as the Second Wrangler in math. This meant he was the second-best math student in his year. He also won the second Smith's Prize, a top award for math and physics. Two years later, he became a Fellow at his college. This gave him a good income and allowed him to continue his studies. In 1819, he became a priest, which helped him keep his fellowship longer.
Changing Math Education at Cambridge
After becoming a Fellow, Peacock started teaching at Cambridge. He felt strongly that the way math was taught at the university needed to change. At the time, Cambridge used an older way of writing calculus. Peacock, along with his friends Charles Babbage and John Herschel, wanted to update this.
In 1815, they created the Analytical Society. Their goal was to bring the newer, more modern calculus methods from Europe to Cambridge. Their first step was to translate a French book on calculus into English in 1816. Peacock then wrote a book of examples for it in 1820. These books helped spread the new methods.
Peacock became a math examiner at Cambridge in 1817. He used this role to introduce the new calculus notation into the exams. This was a big step! Some people didn't like the change, but Peacock was determined. He wrote that he would keep working hard for reform. He believed that by slowly and steadily pushing for change, they could make the university better. His efforts soon led to success for the Analytical Society.
Contributions to Algebra and Science
George Peacock also worked to improve how algebra was taught. In 1830, he published A Treatise on Algebra. This book aimed to make algebra a more scientific subject, bringing it up to date with European mathematicians.
Peacock was also involved in setting up important scientific groups. He, Babbage, and Herschel helped create the Astronomical Society of London. He also helped start the Philosophical Society of Cambridge. He was a strong supporter of building an astronomical observatory at Cambridge.
In 1831, the British Association for the Advancement of Science held its first meeting. Peacock was asked to write a report on the progress of mathematical science. His report, which focused on algebra and trigonometry, was one of the best ever prepared for the Association.
In 1837, Peacock became the Lowndean Professor of Astronomy at Cambridge. This was a very important position. He also worked hard to reform the university's rules and was part of a government group for this purpose. He was elected a Fellow of the Royal Society in 1818 and a member of the American Philosophical Society in 1842.
Clerical Career and Later Life
George Peacock became a deacon in 1819 and a priest in 1822. He served as a vicar in Wymeswold, Leicestershire, from 1826 to 1835.
In 1839, he was appointed Dean of Ely Cathedral in Cambridgeshire. He held this important position for the rest of his life, about 20 years. As Dean, he worked with architect George Gilbert Scott to restore the beautiful cathedral building. They added a new ceiling, among other improvements.
While serving as Dean, he continued his mathematical work. He published a second edition of his algebra book in two parts. One part was called Arithmetical Algebra (1842). The other was On Symbolical Algebra and its Applications to the Geometry of Position (1845).
Ideas on Symbolical Algebra
Peacock's most important idea in math was his effort to make algebra more logical. He helped start the British algebra of logic. This field was later developed by other famous mathematicians like Augustus De Morgan and George Boole.
Peacock believed algebra had two main parts: arithmetical algebra and symbolical algebra.
- Arithmetical algebra deals with symbols that represent numbers. Operations like addition or subtraction only work if the numbers make sense. For example, you can't subtract a larger number from a smaller one in this type of algebra.
- Symbolical algebra takes the rules of arithmetical algebra but removes the limits. This means operations that might seem "impossible" with regular numbers become possible. For example, you can subtract a larger number from a smaller one, and the answer is a negative number.
Peacock called his main idea the "principle of the permanence of equivalent forms." This principle states that if an algebraic rule works for simple numbers, it will also work when the symbols represent more general things. For example, if a rule works for whole numbers, it should also work for fractions or even more complex mathematical ideas. This idea helped mathematicians extend algebra beyond just basic numbers.
Personal Life
George Peacock was a member of the Whig political party. He married Frances Elizabeth Selwyn, but they did not have any children.
His last public act was attending a meeting about university reform. George Peacock passed away in Ely on November 8, 1858, at the age of 67. He was buried in the Ely cemetery.
