Tiedemann was born on 14 October 1872 in Kazan, the son of Genrikh Ottonovich Tiedemann (1839–1889), a nobleman of German Lutheran origin and an Active State Councillor, and Tat’iana Petrovna (née Savel’eva, died 1877), the daughter of a Russian Orthodox doctor.

He was a student intern at the Russian embassy in Beijing (Peking) from 1896 to 1898, when he temporarily took over the consulate in Fuzhou (Foochow) until 1899.

In 1900–01 he served as a secretary and translator at the diplomatic office in Dalian (Port Arthur), capital of the Russian leased territory of Kwantung oblast.

[1] In 1910 he sent Saint Petersburg scathing and detailed reports of the effect of the Portuguese Revolution in Macau, especially lamenting the anticlerical radicalism of certain elements in the Macanese garrison.
