He was then "requested by the Honorable [Robert] Boyle ... to acquaint the Royal Society with the procedure for the whole experiment", which he did in December 1665 in the Societys Philosophical Transactions.The first blood transfusion from animal to human was administered by Dr. Jean-Baptiste Denys, eminent physician to King Louis XIV of France, on June 15, 1667. He transfused the blood of a sheep into a 15-year-old boy, who survived the transfusion. Denys performed another transfusion into a labourer, who also survived. Both instances were likely due to the small amount of blood that was actually transfused into these people. This allowed them to withstand the allergic reaction. Denyss third patient to undergo a blood transfusion was Swedish Baron Gustaf Bonde. He received two transfusions. After the second transfusion Bonde died. In the winter of 1667, Denys performed several transfusions on Antoine Mauroy with calfs blood. On the third account Mauroy died.Six months later in London, Lower performed the first human transfusion of animal blood in Britain, where he "superintended the introduction in [a patients] arm at various times of some ounces of sheeps blood at a meeting of the Royal Society, and without any inconvenience to him." The recipient was Arthur Coga, "the subject of a harmless form of insanity."
He followed this up with four subsequent transfusions in the following months, and his success was reported to Sir Walter Morley Fletcher, director of the Medical Research Committee. Robertson published his findings in the British Medical Journal in 1916 and, with the help of a few like-minded individuals (including the eminent physician Edward William Archibald (1872–1945), who introduced the citrate anticoagulant method), was able to persuade the British authorities of the merits of blood transfusion. Robertson went on to establish the first blood-transfusion apparatus at a Casualty Clearing Station on the Western Front in the spring of 1917.Oswald Hope Robertson, a medical researcher and U.S. Army officer, was attached to the RAMC in 1917, where he became instrumental in establishing the first blood banks in preparation for the anticipated Third Battle of Ypres. He used sodium citrate as the anticoagulant; blood was extracted from punctures in the vein and was stored in bottles at British and American Casualty Clearing Stations along the Front. Robertson also experimented with preserving separated red blood cells in iced bottles. Geoffrey Keynes, a British surgeon, developed a portable machine that could store blood to enable transfusions to be carried out more easily. Expansion
The secretary of the British Red Cross, Percy Oliver, established the worlds first blood-donor service in 1921. In that year, Oliver was contacted by Kings College Hospital, where they were in urgent need of a blood donor.
