by Arnold Steffens
Born on March 30, 1851, in Niederzier, Arnold Steffens was ordained a priest in 1876 and went on to build a respected career in the Archdiocese of Cologne. He later became a vicar at Cologne Cathedral, a cathedral canon, and the head of the diocesan museum.
Alongside his church work, he wrote on religious and historical subjects. Project Gutenberg lists him as the author of Die selige Christina von Stommeln, a work on the 13th-century mystic Christina of Stommeln.
Steffens died in Cologne on September 19, 1923. He is remembered as both a clergyman and a careful steward of the region's Christian art and history.
