Gelfand and Neumark: representing normed rings by Hilbert-space operators

What changed

Developed a representation of the stated class of normed rings with involution as operator rings on Hilbert space, forming a foundation for C-star algebra theory.

Scientific scope

The record is the exact 1943 Matematicheskii Sbornik paper and its normed-ring representation. Later C-star algebra terminology, commutative duality formulations and subsequent operator-algebra developments remain separate.
