David Gur was born in 1926 in Okany, southeastern Hungary, to a family of four. After matriculation he joined the Hashomer Hatzair movement in Budapest, where the organization was compelled to act under illegal conditions. After the occupation of Hungary by the Germans in 1944 he went underground by means of Aryan documents. He joined the underground workshop team for forging documents, and in due course he took over the chief authority for the continual operation of the workshop. This workshop served the clandestine activities of all of the Jewish youth movements, and of the Zionist Organization, and unaffiliated Jews, and most of the non-Jewish resistance groups. The Hungarian Zionist Youth Movement engaged in massive resistance and rescue operations during the Holocaust. Their work included warning other Jews of impending deportations, the manufacture and distribution of false papers and the establishment of safe homes for children.

At the end of December 1944 David Gur was arrested and all the contents of the workshop were confiscated. He was liberated from the central military prison of Budapest by his comrades by means of a daring exploit. He emigrated to Israel in the year of 1949. In 1956 David graduated the Technion, Haifa, as civil engineer.

In the year 1985 David Gur was one of the founders of The Society for the Research of the History of the Zionist Youth Movement in Hungary and since then he holds the position of the executive president.

In 2016 he wrote a book presenting the history of this age, called ˝Együtt az ár ellen/ Together against the tide˝. 

David Gur is turning 92 on the 20th of March, 2018.
