Recently, I have encountered two different accounts explaining the origins of the name "barbituric acid". Both accounts do mention that the name of this compound was given by the famous organic chemist Adolf von Baeyer. Li mentions that von Baeyer named the compound after his girlfriend at the time, with the name Barbara$^{1}$. Quin & Tyrell, on the other hand, informs that von Baeyer named the compound after the patron saint of artilleryman, St. Barbara$^{2}$. This is a seemingly trivial question but I'm genuinely just curious.
