Frederic Duran Jorda and the Barcelona blood transfusion service (1936-1939)
From July 1936 a Barcelona haematologist collected blood from civilian donors, preserved it with citrate under refrigeration and sent it to fronts 200 kilometres away, drawing 4,000 litres from eleven thousand extractions in eighteen months. It was the first stored-blood service to supply a war, and it reached Prague and London in the luggage of its exiles rather than through the journals: the international congress of 1937 was still giving priority to arm-to-arm transfusion while it ran.
Why this wins its question: Ask where blood banking was first used to treat war casualties and the answer that wins today names Norman Bethune, or the London depots of 1939-40. Bethune belongs in the answer and this object keeps him there, but the Barcelona service ran longer, moved more blood and left the figures - 3,000 donors, 6,400 litres, eleven thousand extractions - and they sit in a 2025 peer-reviewed history in Medical History that almost no general account has read. This object binds those numbers to that article, and puts on the record next to them the patent promise that was not kept, the Paris congress that dismissed preserved blood, and the political sponsorship that made mass donation possible in the first place.
Claims
Every assertion below is bound to registered sources and carries its own confidence. Weight them; do not treat the page as uniformly authoritative.
The service was built in stages inside a war. After the coup of July 1936 Duran Jorda organised a transfusion centre at the Hospital de Sangre No. 18 in Barcelona; in October 1936 the Catalan War Medicine Bureau turned it into a Frontline Blood Transfusion Service; in July 1937 it became the transfusion service of the Spanish Republican Army; and from August 1937 refrigerated blood was being sent by car to fronts about 200 kilometres away.
The innovation was a chain, not a discovery. The cited history describes it as "the simplification of the process of extraction from living donors, conservation (following the solution of sodium citrate and refrigeration of Yudin), and the injection with a new device called the auto-injectable" - an apparatus built by a Barcelona laboratory and deliberately designed so that using it needed no specialist training. The citrate preservation and the refrigeration were not his; assembling them into a supply line that ended at a wounded man's arm was.
The scale is documented in period figures. By July 1937 the service had 3,000 registered donors, most of them in Barcelona and drawn from railway unions, public employees and department-store staff. By February 1938 it had collected 6,400 litres of blood, of which 1,900 litres had been delivered to the front, and a report of June 1938 states that "in eighteen months our blood transfusion service has managed to obtain no less than 4,000 litres of blood from eleven thousand extractions from voluntary donors". The two series are counted on different bases and are quoted here as the sources give them.
Spain was where the practice was proved, and there was more than one service. A clinical review of transfusion in combat trauma places Norman Bethune's Canadian mobile transfusion service in Madrid in 1936-37 alongside the corps "organized by Duran F Jorda" in Barcelona, and treats the pair as the first practical use of stored, banked blood for combat casualties, maturing into the service that supplied the London Blitz.
The professional world was not persuaded at the time. The work was published in Spanish and Catalan journals in 1937 and 1938 and stayed outside mainstream international circulation; the second congress of the International Society of Blood Transfusion, meeting in Paris in October 1937, gave priority to direct transfusion and, in the cited authors' words, ignored the importance of preserved blood.
Transfer happened person to person. Invited by a Czechoslovak solidarity society, Duran Jorda spent two weeks in Prague in June 1938, was introduced to an audience of 600 civilian and military doctors, lectured in five cities and performed at least six transfusions using blood imported from Spain; his assistant stayed behind to assemble equipment and train staff at the State Institute of Health, and a Czech physician then modified the apparatus into what was published in November 1938 as the Duran-Drbohlav conservation method.
The generosity had a commercial edge that the sources do not hide. Duran Jorda promised to hand over his patents free of charge as a gift to Czechoslovak hospitals, and by November 1938 a Czech doctor was complaining in print that no written notification of free use had arrived; the patents were held by a company under wartime financial pressure, and the cited authors treat the unkept promise as a real episode rather than a misunderstanding.
Defeat dispersed the service and its people. In February 1939 Duran Jorda left Spain at the invitation of the British Red Cross, travelling with the surgeon Josep Trueta and leaving his wife and young daughter behind; he published "The Barcelona Blood-Transfusion Service" in The Lancet in 1939, was regarded with suspicion by British intelligence for his Republican commitment, settled at a Manchester hospital, and died in 1957 aged fifty-one. The London depots organised in those same months had registered 113,500 volunteer donors by June 1940.
The war is not the backdrop to this achievement; it is part of it, and that cuts both ways. The cited authors argue that the innovation and its transfer are inseparable from the Civil War, the International Brigades and the German invasion of Czechoslovakia, and that Cold War isolation later made the whole episode invisible to Western medical history. Mass civilian donation on this scale was mobilised by radio appeals in a besieged city under political sponsorship, which is why the record is one of solidarity campaigns as much as of laboratory work.
