(Department of Mathematics and Statistics, Amherst College, Department of Mathematics and Statistics, University of Vermont) Carl Friedrich Gauss is often given credit for providing the first correct proof of the fundamental theorem of algebra in his 1799 doctoral dissertation. However, Gauss’s proof contained a significant gap. In this paper, we give an elementary way of filling the gap in Gauss’s proof. On Gauss's First Proof of the Fundamental Theorem of Algebra
