# Origin of the name of barbituric acid

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.

Interesting question but the sad answer is we will never know the true story. Here is the original text (thanks to Google Books) dated 1863, right from the horse's mouth Adolf von Baeyer.

Dieser Gedanke hat mich bei der folgenden Arbeit geeitet (spelling?), und ich habe mich zunächst bemüht, die Kenntnis des Materials zu vervollständigen. Man wird sehen, wie sich dasselbe in einfachster Weise um die Substanz $$\ce{N2CO3H4}$$, die ich Barbitursäure nennen will, gruppieren lässt und wie also die Frage nach der Konstitution der Harnsäure und ihrer Derivate auf die Untersuchung dieser Substanz zurückgeführt ist.

[DeepL Translation] This thought led (?) me to the following work, and I first tried to complete the knowledge of the material. One will see how the same can be grouped in the simplest way around the substance $$\ce{N2CO3H4}$$, which I want to call barbituric acid, and how the question of the constitution of uric acid and its derivatives can be traced back to the investigation of this substance.

He never explained his choice- no footnotes anywhere. However the unabridged Oxford English Dictionary (not open access) attributes it to a woman's name Barbara.
