A Russian immigrant, Armais Arutunoff, who invented the submergible pump, established the Bart Manufacturing Company at Bartlesville in 1928. He later changed his company\'s name to the REDA (an acronym for Russian Electrical Dynamo of Arutunoff) Pump Company. As president and chair of the board, Arutunoff sold his company to TRW, Inc., in 1969. TRW REDA Pump was a major manufacturer of submergible pumps used in the petroleum industry. The firm became Schlumberger-REDA Production Systems in the late 1990s. (From Oklahoma history site.)
