John Monash was born in Melbourne on 27 June 1865. He was dux of Scotch College and studied arts and engineering at Melbourne University, where he was also involved in debating and student politics. Outside of university he dabbled in acting. In 1884 he joined the university company of the 4th Battalion, Victorian Rifles.

Monash worked on the construction of the Princes Bridge in Melbourne and in 1888 was placed in charge of constructing a new railway even though he had yet to complete his degree. Monash married Hannah Moss in April 1891. He finished his studies in 1895 and, having decided to combine engineering with a military career, was promoted to captain in the Garrison Artillery that year. In 1897 Monash was promoted to major in the North Melbourne Battery and served there for 11 years.

Meanwhile, he and a friend had established a private engineering practice in 1894. The business grew steadily but a series of setbacks left him with large debts in 1902. Starting again, Monash recovered and became wealthy. He also gained promotion to lieutenant colonel in the Australian Intelligence Corps, in which he served from 1908 to 1913, when he wore this badge. Now prospering in business and the Army, in 1913 Colonel Monash took command of the 13th Infantry Brigade.

After the outbreak of war, Monash took command of the AIF's 4th Infantry Brigade, landing at Gallipoli on 26 April 1915. In July he was promoted to brigadier. Monash took his brigade to France in June 1916. He became a major general in July and took command of the 3rd Division. The division's first major battle, Messines, was hailed as a great success. Further success followed and in May 1918, Monash was promoted to lieutenant general and given command of the Australian Corps. His first battle in this role, Hamel, came to be considered the 'perfect battle'. Monash remained in command through the victorious battles in the last months of the war.

After spending eight months in London overseeing the repatriation of the AIF, Monash was welcomed home in Melbourne by an enthusiastic public on Boxing Day 1919. He returned to business and in 1920 became manager of Victoria's State Electricity Commission. An advocate for returned soldiers, Monash also held a range of high-level positions. His opinions were widely sought and he became a leading figure in Melbourne's Jewish community.

Monash died of heart disease in Melbourne on 8 October 1931 and was given a state funeral attended by some 250,000 mourners.
