It was a difficult decision for Rademacher, particularly since Hecke was so keen for him to stay in Hamburg. Had Hecke succeeded in his attempt to get Hamburg to offer Rademacher an ordinary professorship then he would almost certainly have remained there, but the university would not make the offer that Hecke requested and, after much thought, Rademacher went to Breslau.
Ito ay isang mahirap na desisyon para sa Rademacher, lalo na dahil Hecke kaya ay masigasig para sa kanya upang manatili sa Hamburg. Had Hecke Tagumpay sa kanyang pagtatangka upang makakuha ng Hamburg na nag-aalok ng Rademacher isang karaniwang pagkapropesor pagkatapos ay siya ay halos tiyak may ay nanatili doon, ngunit ang unibersidad ay hindi ang nag-aalok na Hecke hiniling at, matapos marami-iisip, Rademacher napunta sa Breslau.
