Ottomar Gern
Russian fortification engineer (1827–1882)
Ottomar Borisovich Gern (Russian: Оттомар Борисович Герн; 16 November 1827 – 9 November 1882) was a Russian fortification engineer. Gern was born to a Polish noble family of German origin in Vitebsk Governorate, Russia. He studied war engineering at school and later became a lecturer in the field of construction of fortifications.
During the Crimean War in 1854, Gern was sent to Tallinn to organise better protection for batteries. Gern built four submarines during his life. After the Franco-Prussian War (1870–1871), he made a comprehensive presentation of the protective construction operations of both sides. He was awarded the rank of Lieutenant-General.

In summer 1854, Gern arrived in Tallinn to strengthen the local defence facilities. After a couple of months, the Crimean War (1853–1856) had reached a point where the British and French allies of Turkey has reached the Gulf of Finland, and Russia announced a naval blockade. The British warships were stationed near Naissaar, blocking the exit route from Tallinn.
