Carl Friedrich Gauss (1777-1855)

Carl Friedrich Gauss is considered one of the greatest mathematicians of modern times. His contemporaries called him the "Prince of Mathematics." He was born into a poor family; his father made a living as a mason. As a very small child, Gauss found a calculation error in his father's accounts, the first of many incidents that gave evidence of his mathematical precocity. At 19, Gauss demonstrated that the regular 17-sided polygon can be constructed with compass and straight edge alone. This was remarkable, because, since the time of Euclid, it was though that the only regular polygons constructible in this way were the triangle and the pentagon. Because of this discovery Gauss decided to pursue a career in mathematics instead of languages, his other passion. In his doctoral dissertation, written at the age of 22, Gauss proved the Fundamental Theorem of Algebra: A polynomial of degree n with complex coefficients has n roots. His other accomplishments range over every branch of mathematics, as well as physics and astronomy.
