Saul Winstein

Saul Winstein (October 8, 1912 – November 23, 1969) was a Jewish Canadian chemist who discovered the Winstein reaction. He argued a non-classical cation was needed to explain the stability of the norbornyl cation.^[1] This fueled a debate with Herbert C. Brown over the existence of σ-delocalized carbocations. Winstein also first proposed the concept of an intimate ion pair.^[2] He was co-author of the Grunwald–Winstein equation, concerning solvolysis rates.^[3]
