Marcelle Lapicque

Marcelle de Heredia Lapicque (17 July 1873 – 1960) was a Black-Cuban French neurophysiologist known for her research on nerve impulses (chronaxie) and the effects of poisons on the neuromuscular junction. She supervised the Laboratoire des Hautes-Études General Physiology laboratory, and published many papers - with her husband, alone, and as a mentor to women.

She studied science at the Sorbonne and was a prominent student of Louis Lapicque, whom she married in 1902. Lapicque completed her dissertation in 1905 on nerve impulses, in which she was supervised by her husband. Louis Lapicque "insisted on the importance of his wife as equal co-worker in all his research".

Lapicque published eighty papers with her husband and his students, but her name is not remembered, for a variety of reasons.
