Mathematician:Wilhelm Johann Eugen Blaschke

Mathematician
Austrian differential and integral geometer.

Published one of the first books devoted to convex sets: Kreis und Kugel.

Made a thorough review of the subject with citations within the text to attribute credit in a classical area of mathematics.
