Geoffrey Donaldson was born in 1893. He was educated at Oundle School and Caius College, Cambridge, Donaldson and intended becoming a botanist.
On the outbreak of the First World War, Donaldson, instead of returning for his final year at university, he volunteered for the British Army, and became an officer in the Warwickshire Regiment. Donaldson was sent to the Western Front and in March 1916 he was promoted to the rank of captain and became commander of C Company.
In July 1916, Donaldson became involved in the offensive near Neuve Chapelle. This was a diversionary move to attract German troops away from the Somme. Donaldson realised that he faced a high chance of being killed and wrote to his mother on the day before the attack, that there was an "urgent need of drastic measures on our front to hold back Hun reinforcements for the South and to do this certain troops had to be, well, more or less sacrificed." The following day on the 19th July 1916, Geoffrey Donaldson was killed while leading his men across No Man's Land
