Yemelyan Pugachev
Yemelyan Ivanovich Pugachev () (c. 1742 – ) was a Russian Cossack who led a great popular insurrection during the reign of Catherine the Great, claiming to be her late husband, Emperor Peter III. Alexander Pushkin wrote a notable history of the rebellion, "The History of Pugachev", and he recounted some of the events in his novel "The Captain's Daughter" (1836).
Alexei Turchaninov
During Pugachev's Rebellion (1773—1775) he organized the defences and led the people himself. Turchaninov managed to repel all the attacks by the rebel forces, preventing them from advancing further to Yekaterinburg. Mostly due to these acts of bravery Catherine the Great granted him nobility in 1783. His new coat of arms included "a silver heron holding a stone". The image of a heron was used as a brand of the metallurgical plants in the Sysert Mining District till the 20th century.
