Abstract
MR. S. B. DONKIN, president of the Institution of Civil Engineers, presented the James Alfred Ewing Medal to Mr. Charles Samuel Franklin immediately before the delivery of the James Forrest Lecture by Sir Frank Smith. This Medal was founded in 1936 in memory of Sir Alfred Ewing, an honorary member of the Institution, and is awarded for specially meritorioLis contributions to the science of engineering in the field of research, on the recommendation of the presidents of the Royal Society and of the Institution of Civil Engineers. Mr. C. S. Franklin is well known for his inventions and developments in connexion with beam wireless. The rotating beam aerials installed experimentally at Poldhu in Cornwall were designed by him, whilst he was also responsible for the concentric feeder system for supplying energy to radio aerials and enabling extremely high-frequency Currents to be transmitted along a line without loss. These feeders are used in the beam system and are essential to television transmission circuits.
