María Pilar Izquierdo Albero was a Spanish religious sister born in Zaragoza in 1906. Despite facing severe health challenges, including a long period of blindness and paralysis, she remained dedicated to her religious vocation. In 1939, following what she believed was a miraculous recovery, she established the Missionary Work of Jesus of Mary. Her life was marked by significant physical suffering and service to others during the Spanish Civil War. She died in San Sebastián in 1945 and was later beatified by Pope John Paul II.
