After working 14 years as an English lawyer, I became a Professor of Mathematics at Cambridge.
I published 967 mathematical papers, with my output rivaling that of Euler or Cauchy.
I invented the theory of matrices, though the rectangular structure had been known since 2000 B.C. in China.
I also created the idea of multidimensional abstract geometry involving curves and surfaces.
My other mathematical discoveries include invariant theory, symmetric functions, integral functions, noncommutative group theory, periodic functions, and even some topics in applied mathematics.
I had a worldwide reputation for having an "unending" encyclopaedic knowledge of mathematics.
