Abstract
At the beginning of the twentieth century several Physicists including Poincare and Abraham amongst others were tinkering unsuccessfully with the problem of the extended electron[1, 2]. The problem was that an extended electron appeared to contradict Special Relativity, while on the other hand, the limit of a point particle lead to inexplicable infinities. These infinities dogged physics for many decades. Infact the Heisenberg Uncertainity Principle straightaway leads to infinities in the limit of spacetime points. It was only through the artifice of renormalization that ’t Hooft could finally circumvent this vexing problem, in the 1970s (Cf. paper by ’t Hooft in this volume).
