Colin MacLaurin (1698-1746)

Colin MacLaurin was born in Scotland, the youngest of three sons. MacLaurin never knew his father, who died when Colin was six weeks old. His mother died when he was nine years old, and an uncle, a parish priest, raised him. He entered university at the tender age of 11 years, having distinguished himself with a natural ability in mathematics as a child. His dissertation, a paper on the mathematics underlying the properties of gravity, was finished just before his fifteenth birthday. He was appointed to a professorship at the University of Aberdeen before he turned twenty. One of his early works entitled The Treatise of Fluxions, was a comprehensive and reasoned defense of Newton's calculus methods, which had come under fire from many more traditional thinkers as lacking a solid foundation. Subsequently, some mathematicians feared that many of the bold claims made by Newton regarding the ability of this new science to address longstanding difficult questions would fall apart under careful examination. MacLaurin's work demonstrated the strength of Newton's work, and alleviated some of these concerns. Current calculus students who make it through a full year of a technical track course will most likely recognize MacLaurin for his development of the MacLaurin series, a special case of the more general Taylor's series, a technique for generating power series representations of non-polynomial functions.
