Philip Ridder
Philip Ridder (Russian: Филипп Филиппович Риддер, tr. Filipp Filippovich Ridder; born in 1759 in Saint Petersburg, Russian Empire - died in 1838 in Riga) was a Russian explorer of German descent who discovered polymetallic ores in north-eastern Kazakhstan.
A town in that region, Ridder, bore Philip Ridder's name from 1786 to 1941, when it was changed to Leninogorsk; however, in 2002, the name was reverted to Ridder. The town is notable as the eastern terminus of European route E40.
