David Theile
Australian swimmer, Olympic gold medallist, former world record-holder, surgeon

David Egmont Theile, AO (born 17 January 1938) is an Australian former backstroke swimmer of the 1950s and 1960s, who won consecutive gold medals in the 100-metre backstroke at the 1956 and 1960 Summer Olympics, the only Australian to do so. He subsequently became a leading surgeon and medical administrator.
Swimming career
Theile was born in Maryborough to Alice and Egmont Theile, who ran a husband and wife medical practice. Both had graduated from the University of Sydney, with his father originally being of German descent. He learnt to swim at the age of five, along with his three sisters after being enrolled in a swimming program by his parents. He developed a love of swimming, which relieved him from the boredom of the town, as "the local pool gave us something to do".
By the age of 10, Theile was enjoying success at local swimming carnivals, so his father offered to arrange for him to be coached, but left Theile with the choice of coaches. Of the two coaches in the town, Theile chose Arthur Cusack, who had a reputation as a physical training instructor of whom Theile recounted as being "tough and enthusiastic. All my friends avoided him....somehow I sensed that it was an important decision." Cusack turned out to be his lifelong coach. Under the guidance of Cusack, Maryborough Swimming Club challenged the metropolitan clubs in Brisbane for statewide supremacy.

Why this record matters
The phrase “australian swimmer, Olympic gold medallist, former world record-holder, surgeon” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 14, 2026. The linked authority identifier is Q1176824. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1938, 1956 and 1960.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
