Helen "Duffy" Mohler (June 11, 1917- June 13, 2008) was a letterer for St. John Publications, Gold Key Comics, Standard Comics and DC Comics during the Golden, Silver, and Bronze Ages.

Born in China[1], Mohler was the oldest child of George and Georgia (Chiang) Chu of Gloversville, NY. She had five younger brothers. After graduating from Syracuse University, where she majored in Fine Arts and minored in Journalism, she went to New York City, where she worked for Parents Magazine and their Humpty Dumpty publication for children. At one point she was married to artist and penciller William "Red" Mohler, with whom she had a daughter, Liane. They later divorced, and she lived with Nadine French, who also lettered and worked as support staff for St. John. Being a freelance artist gave Mohler the flexibility she needed as a single mother, and she found work with a wide variety of publishers. Throughout her commercial career, she continued her work as a fine artist.
