Etymology: "Ironmen" is the plural of "ironman," and the story of the singular begins with a 1900s baseball pitcher. Joe McGinnity, nicknamed "Iron Man," pitched 48 complete games in a single season, a feat so punishing that the label stuck to him. In the offseason he worked in an iron foundry, which added a second layer to the nickname: he was both a sturdy pitcher and a man who spent his winters doing hard physical labor. The compound itself is simple, formed from "iron" and "man," with "iron" used in its older sense of hardness and resistance. The plural follows the regular pattern for compounds ending in "man," so "ironmen" refers to several such tireless competitors. The term later moved well beyond baseball to describe endurance athletes who push through extreme demands.
