Manuel Nunes Formigão was a Portuguese Catholic priest born in Tomar in 1883. He is primarily recognized for his early involvement with the 1917 apparitions of Our Lady of Fátima, where he interviewed the three shepherd children. As a witness to the Miracle of the Sun, he became a significant figure in developing the theological understanding of these events. He later founded the Sisters of Reparation in 1927 and became a prolific writer regarding the Fátima messages.
