Editing European bison (section)

===World War II===
Heck gained the support of then ''Reichsjägermeister'' [[Hermann Göring]], who hoped for huntable big game.<ref>Irina Steinmann: [[Nils Seethaler]] hat zur Person Julius Riemer geforscht. In: Wittenberger Sonntag vom 10. Mai 2019.</ref> Heck promised his powerful supporter in writing: "Since surplus bulls will soon be set, the hunting of the Wisent will be possible again in the foreseeable future". Göring himself took over the patronage of the German Professional Association of Wisent Breeders and Hegers, founded at Heck's suggestion. Kurt Priemel, who had since resigned as president of the International Society for the Preservation of the Wisent, warned in vain against "manification". Heck answered by announcing that Göring would take action against Priemel if he continued to oppose his crossing plans. Priemel was then banned from publishing in relation to bison breeding, and the regular bookkeeper of the International Society, Erna Mohr, was forced to hand over the official register in 1937. Thus, the older society was effectively incorporated into the newly created Professional Association. After the Second World War, therefore, only the pure-blooded bison in the game park [[Springe]] near Hanover were recognised as part of the international herd book.<ref>Urmacher unerwünscht.
