He was the fourth son of the first Baron Avebury and his second wife, Alice, daughter of General Fox-Pitt-Rivers. He was educated at St. Aubyns, Rottingdean, and afterwards at Eton. He matriculated from Trinity College, Cambridge where he took his degree as Master of Arts in 1909. After leaving University he followed the family profession of banking, and after some years became a partner in the firm of Coutts and Company, with which his father the first Lord Avebury, and his brother, the present peer have so long been associated. He held a commission with the West Kent Yeomanry and at the outbreak of war, he was at once called up and took part in the Gallipoli expedition, accompanying them as adjutant. He took part in the hardships of that campaign having landed at Cape Hellas and was engaged in that locality until the evacuation. Afterwards he saw service in Egypt and Palestine, and while there was promoted to the rank of Captain. In July 1917 he transferred to the Grenadier Guards and embarked with them to France on the 28th December 1917. He took part in the resistance to the great offensive on the 21st March 1918, and in the second Battle of the Somme, and he was killed instantly by a shell whilst in the front line on the morning of the 4th April, just south of Arras and was buried near Ticheux. A brother officer writes:- Wherever he went he introduced the most valuable element. Whatever the conditions he was always alert, quick and keen, and strongly infected others with the same qualities. War was repulsive to him in every way, yet he never showed it, and so the vitality and charm which he radiated was merely a natural joie di vie, but sprang from the heart of real courage and fortitude.” All who knew him testify to his splendid qualities both as a man and an officer. He seems to have been fearless to a fault, and as sound and capable as he was brave. The urbanity and charm which characterised his father, the first Baron Avebury, better known to his own generation as Sir John Lubbock, the eminent scientist and author, were reproduced in his son, who inherited the keen business instincts of his race. He was devoted to hunting and, before coming to Langham, hunted several seasons with the V.M.H. He was married on 10th June 1914 to Dorothy Charlotte, elder daughter of the Right Hon. H. W. Foster, M.P., and he left two children, John, born 13th May 1915 and Ursula Moyra, born 5th December 1917. His late father the first Baron Avebury was better known as Sir John Lubbock the eminent scientist and author.
