Hagen was a German mathematician who studied applied mathematics and astronomy throughout his lifetime. He worked in Prairie Du Chien, Wisconsin, Georgetown, Washington D.C., and was in charge of the Vatican Observatory for the last twenty-five years of his life ("Father Johann Georg Hagen", Smithsonian Institution Archives).

He was called to serve as the Director of the Georgetown University Observatory in 1888. There he continued his research and published numerous articles and texts. In 1906, John was called by Pope Pius X to take charge of the Vatican Observatory in Rome. He died in Rome on September 6, 1930.
