 versity; National Defense Research Committee, 1943-46; Engaged in 

 air-blast and earth-shock tests at Princeton University Station and ( 

 measurements of air blast at Bikini atom bomb tests; Bell Telephone 

 Laboratories, 1947-. Photoelastic and mathematical stress analysis. Dis- { 

 location theory and problems of plastic deformation were early studies. 

 Later involved with theory of flow and space charge of holes and elec- 

 trons and with electrical and mechanical effects of dislocations and other 

 imperfections in semiconductors. Author of "Dislocations in Crystals,"

 waves, artificial ground systems for short wave reception, angle of arrival 

 of transatlantic short wave signals, multiple unit steerable antenna sys- 

 tem, microwave radio circuits, noise factors in microwave silicon recti- 

 fiers, broad band balanced and unbalanced crystal converters, radar, 

 propagation of microwaves over land paths, angle of arrival of micro-
