Short answers, pulled from the story.
Augustine of Hippo was born on the 13th of November 354 in Thagaste, a municipium in the Roman province of Numidia, in the region that is now Souk Ahras, Algeria. His family were Berbers who spoke only Latin at home and held Roman citizenship for at least a century before his birth.
Augustine of Hippo is known as the Doctor of Grace, Doctor Gratiae in Latin. The title reflects his influential teaching on the necessity of unmerited, prevenient grace for salvation and his extensive writings on the nature of original sin.
Augustine was a Manichaean for approximately nine years before his conversion to Christianity. He was never an initiate or "elect" in the Manichaean hierarchy but held the lowest rank, that of "auditor." His scepticism began after a disappointing meeting with the Manichaean bishop Faustus of Mileve.
Ambrose of Milan baptized Augustine and his son Adeodatus on Easter Vigil, the 24th-the 25th of April 387. Augustine had first approached Ambrose in Milan, initially drawn by his reputation as an orator rather than by theological conviction.
The Confessions is an autobiographical account of Augustine's life and spiritual journey, written in 397-398. It is considered the first Western autobiography and also addresses philosophical topics including the nature of time, causality, and free will. It includes the account of his conversion, prompted by hearing a child's voice say "take up and read."
Augustine died on the 28th of August 430. At the time, the Vandals were besieging Hippo Regius, the city where he had served as bishop. He spent his final days in prayer and requested that the penitential Psalms of David be hung on his walls. His library and cathedral were left untouched when the Vandals later burned the city.
