David Milman (1912-1982)

David Milman was a mathematician who helped develop the geometry of Banach spaces and the use of extreme points in functional analysis. He studied with Mark Krein in Odessa and later worked at Tel Aviv University. Their Krein-Milman theorem describes a compact convex set through the closed convex hull of its extreme points.^[ref] He also proved that a uniformly convex Banach space is a reflexive Banach space. This connection makes a geometric property of the norm control a duality property of the entire space.
