He made contributions to celestial mechanics, statistics, number theory, algebra, and the philosophy of mathematics.

Early lifeEdit

He was born in Salem, Massachusetts, the son of first cousins Benjamin Peirce (1778–1831), later librarian of Harvard, and Lydia Ropes Nichols Peirce (1781–1868).<ref>Template:Cite book</ref>

After graduating from Harvard University in 1829, he taught mathematics for two years at the Round Hill School in Northampton, and in 1831 was appointed professor of mathematics at Harvard. He added astronomy to his portfolio in 1842, and remained as Harvard professor until his death. In addition, he was instrumental in the development of Harvard's science curriculum, served as the college librarian, and was director of the United States Coast Survey from 1867 to 1874. In 1842, he was elected as a member of the American Philosophical Society.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> He was elected a Foreign Member of the Royal Society of London in 1852.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

ResearchEdit

Benjamin Peirce is often regarded as the earliest American scientist whose research was recognized as world class.<ref>Template:Cite journal </ref> He was an apologist for slavery, opining that it should be condoned if it was used to allow an elite to pursue scientific enquiry.<ref>Template:Cite journal</ref>

MathematicsEdit

In number theory, he proved there is no odd perfect number with fewer than four prime factors.

In algebra, he was notable for the study of associative algebras. He first introduced the terms idempotent and nilpotent in 1870 to describe elements of these algebras, and he also introduced the Peirce decomposition.

In the philosophy of mathematics, he became known for the statement that "Mathematics is the science that draws necessary conclusions".<ref>First line of Linear Associative Algebra</ref> Peirce's definition of mathematics was credited by his son, Charles Sanders Peirce, as helping to initiate the consequence-oriented philosophy of pragmatism. Like George Boole, Peirce believed that mathematics could be used to study logic. These ideas were further developed by his son Charles, who noted that logic also includes the study of faulty reasoning. In contrast, the later logicist program of Gottlob Frege and Bertrand Russell attempted to base mathematics on logic.

StatisticsEdit

Peirce proposed what came to be known as Peirce's Criterion for the statistical treatment of outliers, that is, of apparently extreme observations. His ideas were further developed by his son Charles.<ref>Peirce, Charles Sanders (1870/1871/1873).</ref>

Peirce was an expert witness in the Howland will forgery trial, where he was assisted by his son Charles. Their analysis of the questioned signature showed that it resembled another particular handwriting example so closely that the chance of such a match occurring at random, i.e. by pure coincidence, was extremely small.<ref>Template:Cite journal</ref>
