Why Is Per Enflo Influential?

(Suggest an Edit or Addition)

According to Wikipedia, Per H. Enflo is a Swedish mathematician working primarily in functional analysis, a field in which he solved problems that had been considered fundamental. Three of these problems had been open for more than forty years:The basis problem and the approximation problem and laterthe invariant subspace problem for Banach spaces.In solving these problems, Enflo developed new techniques which were then used by other researchers in functional analysis and operator theory for years. Some of Enflo's research has been important also in other mathematical fields, such as number theory, and in computer science, especially computer algebra and approximation algorithms.
