Isidoro Zorzano Ledesma (13 September 1902 – 15 July 1943) was a Spanish Roman Catholic member of Opus Dei. Zorzano was a naturalized Argentine due to being born in Buenos Aires though upon his relocating to Spain met and befriended Fr Josemaría Escrivá and soon joined the latter's embryonic foundation, which would later become the first personal prelature of the Catholic Church. He worked as an engineer and worked in several places though his compassion and love for the poor led people around him to name him as a saint due to his efforts in alleviating their suffering through various means; he aided priests and Opus Dei alike during the Spanish Civil War and he himself kept to himself for most of that period to avoid being targeted and killed.
