Caritas Pirckheimer was Abbess of Saint Clara's convent in Nuremberg at the time of the Reformation, which she opposed due to the threat posed by Martin Luther to Catholic houses of worship and religious buildings, including her own convent. Born in Eichstätt as Barbara Pirckheimer, she was the eldest of 12 children, nine of whom would survive to adulthood and one of whom was the prominent humanist Willibald Pirckheimer. Wikipedia
