Philip Ridder (1759 - 1838) was a Russian explorer 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.
Until 1941 it carried its present name, named after Philip Ridder who discovered the local ore deposits.
