The award was given posthumously to Yandell, who died in 2004.[6] 2009: Siobhan Roberts, King of Infinite Space: Donald Coxeter, the Man Who Saved Geometry (Walker and Company, 2006).[1] This biography of Harold Scott MacDonald Coxeter also describes the history of geometry and Coxeter's contributions to the field.[7][8] 2010: David S. Richeson, Euler’s Gem: The Polyhedron Formula and the Birth of Topology (Princeton University Press, 2008).[1] Richeson relates the history of Euler's formula V − E + F = 2 connecting the numbers of vertices, edges, and faces of a convex polyhedron. The story leads from Euler's first observation in 1750 to modern topology and the mathematics of William Thurston and Grigori Perelman.[9] 2011: Timothy Gowers, The Princeton Companion to Mathematics (Princeton University Press, 2008). This book provides an overview of modern research mathematics; Gowers edited the contributions of 133 distinguished mathematicians as well as writing many of the entries in it himself.[10] 2012: Daina Taimiņa, Crocheting Adventures with Hyperbolic Planes, A.
