Louisa Stammwitz (1850 – 1916) was a British pharmacist whose campaigning contributed to the admission of women to the Pharmaceutical Society of Great Britain,[1] along with the efforts of Rose Minshull, Alice Hart, and Isabella Clarke.

[4] After passing the Preliminary examination in pharmacy in 1873, Louisa Stammwitz and Rose Minshull worked as dispensers at a clinic run by Elizabeth Garrett Anderson.

Stammwitz and Minshull applied again, and were rejected again, in 1877 when they had passed the Minor examination and registered as chemists and druggists.

Stammwitz came second out of a class of eight, of whom four failed the exam, and she was received with a rendition of 'See, the Conquering Hero Comes' by her fellow students when she was given her certificate.

[9][2] She then opened a pharmacy in Paignton, Devon with Annie Neve, a former apprentice of Isabella Clarke who had qualified as a pharmacist in 1884.
