Hertzberg, Charles Sumner Lund, 1886-1944 : Charles Sumner Lund Hertzberg (1886-1944) was raised and educated in Toronto, Ontario, graduating in engineering from the University of Toronto in 1905. A civil and structural engineer, his first jobs included railway survey work with the Canadian Pacific Railway in Ontario and Quebec, and from 1908 design work with the Trussed Concrete Steel (Truscon) Company of Walkerville, Ontario. In 1912 he went to Toronto as manager of the Bishop Construction Company.
C.S.L. Hertzberg had a keen interest in the Militia. He had enlisted in 1903 with the Second Field Company, Canadian Engineers at Toronto and obtained a commission in that unit in 1904. When his work took him away from Toronto, he was attached to other militia units, serving at various times with the Winnipeg Grenadiers and as the Signals Officer to the Essex Fusiliers. From the outbreak of the First World War until late in 1915, he was employed on duties in Canada. On the formation of the 3rd Canadian Division, he was made an officer in the 7th Field Company, Canadian Engineers and went to France in 1916. For his services on the Somme Front, he was awarded the Military Cross. Early in 1917, he was dangerously wounded, and after several months of hospitalization was invalided home.
On the formation of the Canadian Siberian Force in 1918, C.S.L. Hertzberg was named the Senior Engineer Officer. There he was responsible for the numerous engineering jobs pertaining to an army of occupation and for these services was awarded the Czech War Cross. In the immediate post-war period, he commanded the Second Field Company and was later the Officer Commanding No. 2 District Engineers in Toronto. He also served as an Aide-de-Camp to Herbert Bruce, Lieutenant-Governor for Ontario.
Following the First World War, he returned to private engineering work. He was a co-founder of the civil consulting firm of James, Loudon and Hertzberg and left that partnership to form a purely structural firm, Harkness, Loudon and Hertzberg, later to become Harkness and Hertzberg. This latter firm carried out the structural design of such notable structures in Toronto as the original Canadian Bank of Commerce Building, the East Block of the Ontario Legislative Building and the Canada Life Building, and the Sun Life Building in Montreal.
From 1939 to until mid-1943, C.S.L. Hertzberg was the senior engineering officer for the Canadian Army Overseas. As the army grew in size from a Division to the First Canadian Army of two Corps, he was promoted from Lieutenant-Colonel to Major-General and Chief Engineer. For his services he was made a Companion of the Order of the Bath. In June 1943, having reached the mandatory retirement age of the Canadian Army, he was forced to relinquish his command. He was then placed on special assignment to the Indian Army to oversee experimental work on air landing strips in India. While in India, he contracted small-pox and died in early January 1944.
