Why do we have the version of Galois theory that we do – why, indeed, do we have Galois theory at all? This talk traces conflicting 19th-century visions of what it would be to solve, or better to understand, polynomial equations and finds the forgotten role of Felix Klein in promoting Galois's ideas in Germany and America.
