CHARLES GORDON HEWITT 
The science of entomology and its devotees have suffered an irrep¬ 
arable loss in the untimely death, on February 29, of Dr. Charles 
Gordon Hewitt, entomologist and consulting zoologist of Canada. 
Dr. Hewitt had held these positions since September, 1909. He was 
the son of Mr. T. H. Hewitt and was born February 23, 1885, at Mac¬ 
clesfield, near Manchester, England. He attended the grammar school 
and later the University of Manchester, where he was a prize student 
and received the degree of Doctor of Science. In 1904 the latter 
institution appointed him lecturer and in 1907 demonstrator in zoology. 
Before leaving England to fill the position of Dominion entomologist 
he had been a member of several scientific societies. Besides studies 
on the larch saw-fly and other insects he had written an excellent mono¬ 
graph on the house-fly under the guidance of his teacher, Prof. Sydney 
J. Hickson. It was first published in three parts in the Quarterly 
Journal of Microscopical Science (1907-09) and in 1910 issued as a 
book by the University Press of Manchester. It remains one of the 
most valuable contributions to a subject of great economic impor¬ 
tance. After taking up his position in Ottawa, Dr. Hewitt married 
Miss Elizabeth Borden, daughter of the former premier, Sir Frederick 
Borden. 
The truly remarkable record of development and public service 
exhibited by Dr. Hewitt’s department during the decade of his admin¬ 
istration was clearly due to the unusual abilities of the man. Combin¬ 
ing a thorough training in zoology with rare gifts as an investigator, 
executive talent of a high order and sympathetic insight into the 
achievements of other workers, not only in entomology but in biology 
generally, he could not fail to secure the affection as w r ell as the con¬ 
fidence and admiration of all the men, and particularly the young 
men, whom he had chosen as aids in building up his department. His 
scientific interests, however, were not confined to his immediate, 
official environment. Realizing that very many of the native and 
introduced animals and the economic problems to which they give 
rise are identical in Canada and the northern United States, he took 
an actively constructive part in all deliberations, wherever men were
