Executive summary
Bob (Robert) Mathias of the United States won the Olympic decathlon at the first Summer Games after WWII (London 1948) at age 17, scoring 7,139 points and later repeating in 1952 [1] [2]. Fanny Blankers‑Koen of the Netherlands was the breakout star in London 1948, winning four golds (100m, 200m, 80m hurdles and 4×100m relay) and becoming the first woman to claim four track-and-field golds in a single Games [3] [4]. Delfo Cabrera is recorded in available sources as the Argentine winner of the 1948 Olympic marathon — not a Great Britain athlete — taking gold after passing a faltering leader on the final lap [5] [6].
1. Bob Mathias: teenage decathlon champion and headline debut
Bob Mathias arrived in London as a near‑unknown who had only recently taken up the decathlon; he won the men's decathlon at the 1948 Games and became the youngest track-and-field Olympic champion at 17, posting a winning total reported as 7,139 points in multiple records of the event [7] [1]. Contemporary and retrospective profiles emphasize his rawness — including a fouled shot put due to unfamiliarity with rules — and his swift ascension into global prominence, later defending his title in 1952 [8] [2] [9].
2. Fanny Blankers‑Koen: the "Flying Housewife" who reshaped women's sport
Fanny Blankers‑Koen dominated the women's athletics programme in London, winning gold in the 100m, 200m, 80m hurdles and the 4×100m relay, a haul described across official and encyclopedic accounts as four gold medals and a defining performance of the 1948 Games [3] [4] [10]. Sources stress the cultural context: she was 30, a mother of two, and faced public skepticism about age and motherhood; her victories were framed as symbolic for post‑war renewal and a turning point for women's athletics [11] [12].
3. Delfo Cabrera: marathon drama and national gold for Argentina
Delfo Cabrera won the Olympic marathon at London 1948 in a dramatic finish, overtaking a flagging Etienne Gailly as he entered the stadium and holding off Tom Richards to take gold for Argentina; this result is recorded consistently in official results and athletics histories [5] [13]. Multiple bios and event pages identify Cabrera as Argentine and make no reference to him representing Great Britain; sources that directly address that question state he represented Argentina [6] [14].
4. Where the original query is correct — and where it contains errors
The query correctly names Mathias and Blankers‑Koen as champions at the first postwar Olympics; both are confirmed winners in their respective events [1] [3]. The error in the query is the national attribution for Delfo Cabrera: authoritative sources list him as an Argentine athlete and London 1948 marathon gold medallist for Argentina — not Great Britain [5] [6]. Available sources do not mention Delfo Cabrera competing for Great Britain (p3_s11 provides explicit contradiction).
5. Notable contemporaries and the broader London 1948 storyline
London 1948 is portrayed across sources as the “Austerity” Games and a stage for new and returning stars: Emil Zátopek emerged for Czechoslovakia, and other champions such as László Papp and Paul Elvstrøm made their marks, underscoring that Mathias and Blankers‑Koen were among several significant debut or breakthrough performances that year [15] [16]. Official Olympic result pages and encyclopedias list full medallists if you want to check other event winners [17] [18].
6. Sources, limitations and competing perspectives
This account relies solely on the supplied documents: official Olympic athlete pages, Britannica, Olympedia, Wikipedia extracts, and sports histories (p1_s1–[21]; [3]–[22]; [23]–[5]; [16]; [24]3). These sources agree about Mathias and Blankers‑Koen’s wins and Cabrera’s marathon gold; they disagree with the query’s claim that Cabrera represented Great Britain [5] [14]. Available sources do not mention any evidence that Delfo Cabrera competed for Great Britain or held British nationality [14]. Where sources offer context — for example, debates about Blankers‑Koen’s age and motherhood — I cite contemporaneous and retrospective reporting that documents those cultural reactions [19] [12].
If you would like, I can extract the official London 1948 athletics winners list and supply the primary event pages for Mathias, Blankers‑Koen and Cabrera so you can see the official results and times/points listed by event [17] [20] [13].
