Imperial Russian Army general (1870–1918)
Source (Wikipedia): Lavr Kornilov

Lavr Georgiyevich Kornilov was a Russian military intelligence officer, explorer, and general in the Imperial Russian Army during World War I and the ensuing Russian Civil War. Kornilov was of Siberian Cossack origin. Today he is best remembered for the Kornilov Affair, an unsuccessful endeavor in August/September 1917 with unclear motives, which led to Alexander Kerensky eventually having Kornilov arrested and charged with attempting a coup d’état, and ultimately undermined Kerensky’s rule.
