Eric Megaw

Eric Christopher Stanley Megaw MBE (1908 – 25 January 1956) was an Irish (Belfast-educated) engineer who refined the power of the cavity magnetron for radar purposes (detection of U-boats) in the Second World War.

He was the son of Arthur Stanley Megaw who married Helen Smith.

[5] After graduating from Queen's at the age of 20, he was awarded a research fellowship at Imperial College, London.

He was the leader of a group working on the cavity magnetron from April 1940 in north-west London.

Eric Megaw changed the design, coating the cathode with oxides (E1189 version)[8] and eight segments from six, to increase the power to 100 kW by September 1940, enough to detect submarines.
