Abstract

BY the death of Dr. Edward Weston on August 20, the electrical industry loses one of its greatest pioneers. Born in 1850, on the border line between England and Wales, he went to the United States when fifteen years old and devoted his energies to studying the action of existing direct current dynamos and making improvements on them. If not the first, he was one of the first to realize the necessity of laminating the iron in the armature of a dynamo so as to obviate the heavy losses that otherwise occurred owing to the eddy currents induced by the alternating magnetic flux. Edison also worked on this problem, and the efficiency of the dynamo was soon raised from 50 to 90 per cent.
