Several days after arriving in Prague in October 1959, Deitch met Zdenka Najmanová, the production manager at the studio Bratři v triku where he worked. They married in 1964. Deitch's memoir, "For the Love of Prague", is based on his experience of being what he called "the only free American living and working in Prague during 30 years of the Communist Party dictatorship". According to Deitch, although he was followed by the StB and his phone was tapped, he was never aware of their presence and was never interrogated nor arrested.
