author
A Catholic priest and museum director in Cologne, he wrote with a strong interest in religious history and local church life. His best-known work, Die selige Christina von Stommeln, reflects that deep focus on devotion, biography, and the Rhineland's spiritual past.

by Arnold Steffens
Born on March 30, 1851, in Niederzier, Arnold Steffens became a Roman Catholic priest and later served as a canon of Cologne Cathedral. He was also closely connected with the Diocesan Museum in Cologne, eventually leading it, and was active in the city's religious and cultural life.
As an author, he is chiefly remembered for Die selige Christina von Stommeln, a work about the medieval mystic Christina of Stommeln. His writing grew out of his church work and his interest in sacred history, combining scholarship with a clear devotional purpose.
Steffens died in Cologne on September 19, 1923. Although he is not widely known today, his work remains of interest to readers drawn to Catholic history, sainthood, and the religious culture of the Rhineland.
