Hermannus Contractus (also known as Herimanus Augiensis or Hermann von Reichenau) was the son of Count Wolverad II von Altshausen. He was born 18 February, 1013 at Altshausen (Swabia). He was a cripple at birth, but intellectually gifted. Therefore his parents sent him to be taught by Abbot Berno on the island of Reichenau. He took his monastic vows here and died on Reichenau 21 September, 1054. He was a mathematician, astronomer, musician, chronicler, and poet, among other things. He is frequently credited as the author of "Alma Redemptoris Mater" and "Salve Regina"
