Mikuláš Végh was born on 17 July 1920 in Košice, Czechoslovakia. He lived in his hometown until his graduation from grammar school. As he wished to study medicine he moved in with relatives in Brno. However, he was not accepted at Brno’s medical faculty due to his Jewish origins and instead enrolled to study construction engineering at the city’s University of Technology.

However, at the start of 1939 Végh had to end his first year studies for racial reasons. As he was not permitted to either study or work anywhere else in Brno he returned to Košice – which had been occupied by Hungary since November 19638 – just a few days before the Nazi occupation of the remainder of Bohemia and Moravia in March 1939. He sympathised with leftist ideology and placed his hope in the Soviet Union, where relatives of his lived. For that reason he left in September 1940, like many refugees from south-eastern Slovakia, for Mukacheve with the aim of in future crossing the border into the USSR.

However, on 26 September 1940 he was arrested while crossing the frontier by Soviet border guards near the village of Vyšný Studený, which lay near the Hungarian-Soviet border.

Végh was first investigated in Skole, where investigators decided on 2 October 1940 to place him in custody. In January 1941 he found himself in prison in the city of Stryi, where his interrogations continued until that April. The Drohobych Oblast prosecutor pressed charges against him on 16 March 1941.

A few months prior to his conviction, from October 1941, he was in custody in a prison in Molotov (today Perm) in the central Urals, where he was probably imprisoned for several more months. He died on 8 June 1942 in Solikamsk in the Urals in the KOLP, a transit prison of the Usollag prison camp complex, where prisoners awaited transfer to other camps. The official cause of death was pneumonia.
