Lavoisier’s wife was called Marie-Anne, and in full Marie-Anne Pierrette Lavoisier, née Paulze, but for the purposes of this narrative she shall be known as Lavoisier’s wife. This is not intended to strip her of her humanity or personhood, as a woman; rather, it is meant to focus a tight and somewhat ironic spotlight on the role she will play in her husband’s drama, and to signal (wink wink nod, as the OED would do) her eventual and historical erasure from it.
