Charles Hertzberg was born in Toronto, Ontario, Canada on 12 June 1886, to Anton Lund Hertzberg and Helen Eliza Hertzberg. He had two brothers - Major General H.F.H. Hertzberg, CB, CMG, DSO, MC of the Canadian Engineers and Lieutenant O. P. Hertzberg, MC of the C.R.T. He was descended from a distinguished military family in Norway, and was the great-grandson of Niels Hertzberg. Hertzberg was educated at St. Andrew's College in Aurora, Ontario, between 1899 and 1901 before earning an engineering degree at University of Toronto in 1905. He joined 2nd Field Company Canadian Engineers in 1902, and was commissioned in 1904. Before heading overseas to fight in the First World War, Hertzberg worked as a consulting engineer a career he continued post-war. His brother, H.F.H. Hertzberg, also reached the rank of Major General. The Hertzbergs were the only brother-duo to hold the rank of general at the same time in the Canadian army. He married Jessie Alexander Hertzberg, of Toronto.
Hertzberg went overseas in 1916 and saw action in France as a Captain of the 7th Field Company of the Royal Canadian Engineers. He suffered a severe chest wounded at Vimy Ridge in 1917 and was awarded the Military Cross for "conspicuous bravery in action" in January of that year. Deemed permanently unfit for any service, he was sent home in June 1917. He then served as Adjutant of the Spadina Military Hospital in Toronto. He managed to make his way back into action in October 1918 at Vladivostok, where he fought with the Canadian Siberian Expeditionary Force as a major, with the title of Senior Engineering Officer. Here he fought the Bolsheviks and was awarded the Slovak Republic's Croix de Guerre for his services in Siberia. He served until the Force demobilized in June 1919.
From 1939 to 1943 Hertzberg was the senior engineering officer for the Canadian Army overseas, forced into relinquishing his command by mandatory age limits. He was the first Canadian to hold the position of Chief Engineer in the Canadian Army. Hertzberg went overseas in December 1939 as Lieutenant-Colonel of the 1st Canadian Infantry Division, tasked with commanding the engineers. He quickly rose to Chief Engineer of the division, and then of the Army, with the rank of Major General. During his command he and the Canadian engineers developed technologies that proved invaluable to the war effort. Hertzberg was favored by General Andrew McNaughton and when he reached the age-limit for his rank, McNaughton asked the Minister to grant Hertzberg a special extension because there was "no other suitable officer" who could replace him. Hertzberg was finally forced into retirement in June 1943. McNaughton wrote at the time: Upon retirement Hertzberg was appointed Companion of the Order of the Bath: Hertzberg died in January 1944 of smallpox at the age of 58 while in India. He was on a special assignment developing an innovative form of portable air landing strip. He was buried in the Delhi War Cemetery. The Canadian Military Engineers award an annual trophy in Hertzberg's name. It is presented annually to the Reserve Engineer unit that successfully completes a stand-alone project of significant training and/or civilian or military community relations value.
Civilian life and private practice
Between the wars Hertzberg built a large structural engineering practice and helped build a number of landmark structures in Toronto, including the original Canadian Bank of Commerce head office, which was at the time the tallest building in the Commonwealth. Hertzberg co-founded the civil engineering consulting firm James, Loudon and Hertzberg. He then broke away from that firm to form a firm specialising in structural engineering: Harkness, Loudon and Hertzberg, which later became Harkness and Hertzberg, a large and prominent Toronto practice. Hertzberg's buildings include:
