Dr.  E.Grinbergs bija viens no pirmajiem tagadējā LU Matemātikas un  informātikas institūta darbiniekiem. Viņa darbi ilgus gadus kalpoja par  pamatu kuģu korpusu projektēšanā visā PSRS.
    From Wikipedia, the free encyclopedia:  „In  graph theory,Grinberg's  theorem is a necessary condition on the  planar graph to contain a   Hamiltonian cycle. The result has been widely used to construct  non-Hamiltonian planar graphs with further properties, such as to give  new  counterexamples to  Tait's conjecture. This theorem was proved by a    Latvian  mathematician  Emanuel Grinberg in 1968.”
