Reginald Frank Jerram (SN 1955) was barely 18 years old when he enlisted at Melbourne, with the permission of his parents, on 21st June 1915. He was unmarried and listed his occupation as "aerated water manufacturer". Posted to the 21st Battallion, his unit embarked from Melbourne on board the Anchises in August. The details of the first few months of his overseas service are unclear but it appears from his medical history that he served in Egypt in late 1915 and was probably involved in the evacuation of Gallipoli in December. In May 1916, he was transferred to the 8th Battalion and posted to France where he was appointed Driver. The next 18 months appear to have passed relatively uneventfully until, in October 1917, he received a gunshot wound to his right thigh and was hospitalised until the end of November. He was admitted to hospital several times during 1918, finally being transferred to Lord Derby War Hospital in Warrington, England, in September with a contusion on his left arm. He left England aboard the Ulysses in January 1919, disembarking in Melbourne in March, and was discharged as medically unfit on 24th May 1919.

His brothers Harry and Leonard also served in the AIF and are honoured with trees in the Avenue.
