Soennecken was born in Iserlohn-Dröschede, Sauerland in 1848, the son of a blacksmith. On May 27, 1875 he founded the F. Soennecken Verlag, a commercial enterprise in Remscheid, Westphalia. His main invention is the "round writing" style of calligraphy and the pen nib associated with it. Round writing was designed to be a visually appealing, standardized style of penmanship which was easy to learn and execute, and Soennecken published books on the topic in several languages.
Soennecken also introduced the two-hole punch and the ring binder. In 1876 he and his company relocated to Poppelsdorf, near Bonn, to be closer to the University which later awarded him the honorary title Dr. med. h. c..
Soennecken died in Bonn in 1919.
