Alicia Boole Stott, a geometer in higher dimension

In this paper we present the life and work of Alicia Boole Stott, an Irish woman who made a significant contribution to the study of four-dimensional geometry. Although she never studied mathematics, she taught herself to “see” the fourth dimension and developed a new method of visualizing four-dimensional polytopes. In particular, she constructed three-dimensional sections of these four-dimensional objects, which resulted in a series of Archimedean solids. The presence in the University of Groningen of an extensive collection of these three-dimensional models, together with related drawings, reveals a collaboration between Boole Stott and the Groningen professor of geometry, P.H. Schoute. This collaboration lasted more than 20 years and combined Schoute's analytical methods with Boole Stott's unusual ability to visualize the fourth dimension. After Schoute's death in 1913 Boole Stott was isolated from the mathematical community until about 1930, when she was introduced to the geometer H.S.M. Coxeter, with whom she collaborated until her death in 1940.
