María Emilia Riquelme was a Spanish religious sister born in 1847 in Granada. After experiencing a vision of the Virgin Mary as a child, she felt a strong calling to religious life. Although her father initially resisted her vocation, she eventually founded the Missionaries of the Blessed Sacrament and the Immaculate Mary in 1896. Serving as the congregation's superior general, she dedicated her life to assisting the poor and establishing educational resources for girls. She died in Granada in 1940.
