Grant was educated at Epsom College - where for six years he was in the Cadet Corps, and at Queen's College, Cambridge, where for three years he was a member of the O.T.C., obtaining Certificates A and B. At Epsom he gained the Brand prize and the Stone scholarship, the former testifying to the esteem in which he was held in respect of his character and conduct. He then entered the London Hospital and studied there for his medical and surgical qualifications. Grant joined the London Scottish as a Private in 1911. He went to war with them, entering in France on 15th September 1914. Soon after he arrived, however, he was transferred to do hospital work and was given a commission at the rank of Lieutenant in the R.A.M.C. He did work for some months as Surgeon on an Ambulance Train and then, at his own request, became attached to the London Scottish as their Medical Officer. He was promoted to Captain on 30th September 1915. Grant was hit on the back of the head by a shell when conducting morning sick parade, and died a quarter of an hour later without recovering consciousness. A telegraph of Royal sympathy was received by his parents. Lt-Col James Lindsay wrote: "It is my sad duty as officer in command of the London Scottish to express to you the intense grief which is felt by all ranks of the regiment at the death of your son, and the deep sympathy which we all feel for you. He was in the act of conducting his morning Sick Parade when a shell burst in the trench, hitting him and five others. He was hit in the back of the head and, though he was not killed at once, there was from the first little hope of saving his life. He died without recovering consciousness. He was a man whom we all admired and loved; always hard-working and efficient, and particularly cool and courageous in action. We shall find it hard indeed to replace him. He had just been recommended for reward for his conduct on 25 Sept". The Chaplain wrote: "Yesterday he was killed, dying the death of the brave, about 10.15 a.m..... He was brought down from the trenches and was buried in the Mazingarbe Cemetery in a separate grave, beside some other officers.... The London Scottish will erect a cross to-day... He was much esteemed by the officers and men in our battalion, and his death has been a great sorrow to us. If recent actions he had done very well and even by his brothers in the R.A.M.C. he was spoken of admirably." Capt Claud Low also wrote: "He was a splendid fellow, and had a very great sense of duty. He would go anywhere, and do anything for the good of the battalion. He had the confidence of every officer and man, and was a true comrade. I offer you my sympathy, and assure you that his life was not wasted. He did a great deal for the good of others. It may seen to you that his life was thrown away at an early age; but only a young man could have done the work he did." And Capt E M Stirling wrote: "His dressing station was always right up where it was most wanted, and he went about his work absolutely fearlessly; and many a poor chap had got him to thank for a speedy recovery from bad wounds. I saw him on the 25th, 26th and 27th Sept., the days of the first big attack. I cannot say enough of the priceless work he put in and the way he kept at it night and day. When it wasn't our men it was some other regiment. He was always at it, and so cheery. We shall all miss him terribly, both in the regiment and the miss - just one of the best. He was, as you doubtless know, a Private with us when we went out. He and Eric Wright - who also, poor fellow, died in Egypt - did the most wonderful wort at Villeneuve St George last autumn, when all the wounded were coming through from the Aisne, and when dressing stations were few and far between. They saved many a man's life there, and in two cases I know of performed amputations. He got his commission as the result, and was for some months on an ambulance train, leaving that to rejoin the Scottish as a doctor. I remember someone, just before this last show, asking him if he were going back to a train when his six months were up, and he replied, 'Not as long as I can remain with the Scottish'." Grant was held in such high esteem a memorial in Mazingarbe was erected by the London Scottish. He was the only son of Leonard (M.D.) and Louisa Grant (daughter of George De Vins Wade) of 5 Weech Road, West Hampstead, London.
