Tuhia he whakamāramatanga mō tēnei wāhanga - I kitea e Franck he tūranga i te "Polytekniske Læreanstalt" i Copenhagen mō Arthur von Hippel, nāna nei i riro hei tāna mokopuna, nā te marenatanga ki tana tamahine a Dagmar. I whakatau ia ki te whakarato i te haumaru pūtea mō ana tamariki mā te wehewehe i te moni o tana Tohu Nobel ki a rātau. I tukua te mētara koura ki a Niels Bohr hei tiaki. I te wā i whakaekea ai a Tiamana ki Rānana
i te 9 Paenga-whawha 1940, i whakakorehia e te kaimatai Hungarian a George de Hevesy te mētara koura, me tera o Max von Laue i roto i te wai kingi kia kore ai e tangohia e nga Tiamana. I whakatakotoria e ia te rongoā i puta mai ki runga i te papa i roto i tana taiwhanga i te Niels Bohr Institute. Whai muri i te pakanga, ka hoki mai ia kia kitea te rongoā kaore i whakararuraru, a, ka whakaheke i te koura mai i te waikawa. Kātahi ka whakarerekētia e te Nobel Society ngā mētara o te Nobel Prize.
