Ridder (Kazakh and Russian: Риддер), formerly known as Leninogorsk (Russian: Лениногорск, 1941–2002) is a city in the East Kazakhstan Province in north-eastern Kazakhstan. Population: 50,500 (2009 Census results). The city is situated in the southwestern Altai Mountains and northeastern of the region's capital, Oskemen, along the Ulba River, at an elevation higher than 1,000 metres.
The fact that Altai Krai is rich in natural deposits was recalled during Empress’ Catherine II ruling. The history of Ridder started in 1786 when 9 troops were sent to Altai to search natural deposits. One of the troops was headed by an officer Philip Ridder. On May 31, 1786, he found a very rich deposit containing gold, silver and other metals.
The same year, in summer, the settlement was founded there and it was named Riddersky pit. This was how the city was founded. Unique ores of Riddersky deposit were marked by specialists of various levels and commissions. The deposit became known far beyond Russian Empire. In 1850, Riddersky ores received the highest appreciation at London World Exhibition, in 1879 the samples were included into the museum collection of Stockholm Royal Technical Institute.
In early 20th century Rudder experienced a number of foreign concessions, revolution and Civil war. On January 1, 1932, the settlement Riddersky became a town. Before World War II the town of Ridder was renamed into Leninogorsk.
