Charles Calvin Ziegler (1854–1930) was a German-American poet from Rebersburg, Pennsylvania.

He is said to have been the most accomplished poet to write in it, and may have written the only Pennsylvania Dutch sonnet on record.

When he was sixteen, Calvin went to join Samuel, eventually graduating the University of Iowa in 1878.

He returned to Rebersburg and pursued teaching, but left again in October 1881 to study Greek and Latin at Harvard.

Included in the volume in a set of nineteen poems devoted to his mother, who died weeks before his Harvard graduation.
