Ladau (1765–1833) was the first Postmaster General of the Grand Duchy of Finland, which was ruled by Russia. He was hard-working, demanding and meticulous, and achieved his goals by maintaining strict discipline. He was also a controversial director who practiced postal censorship and had mail checked in secret. Ladau was an influential leader and thought that Finland should have tight connections with Russia.
Ladau was born into a military family in the Iisalmi parish. He went to Haapaniemi military school and served in the Swedish army. His army career ended in the Anjala conspiracy, and he fled to Russia in 1789, where he served as a captain in the army from 1791–95. After resigning from the army, he served as an estate manager before returning to work in the civil service at the Ministry of Foreign Affairs in 1808. Alexander I of Russia ordered Ladau to organise the postal services system in Finland in 1810.
