Maria Micaela Desmaisières was a Spanish Catholic nun born in Madrid in 1809. Raised in high society due to her brother's diplomatic role, she eventually dedicated her life to assisting marginalized women and the sick. She founded the Sisters of Adoration, Handmaids of the Blessed Sacrament and of Charity in 1845 to provide shelter and support for women facing economic hardship or social exclusion. Her commitment to service continued until her death in Valencia in 1865, where she succumbed to a cholera epidemic while caring for the ill.
