Catherine Anna Yronwode (née Manfredi; May 12, 1947) is an American writer, editor, graphic designer, typesetter, and publisher with an extensive career in the comic book industry.

Her father was Joseph Manfredi, a Sicilian American abstract artist, and her mother, Liselotte Erlanger, a writer, was an Ashkenazi Jewish refugee from Nazi Germany.

[6] Describing herself as "one of those girls who took a look around at what the boys were doing", she quickly became an avid reader of Marvel Comics' Silver Age material, beginning with Fantastic Four and The Amazing Spider-Man.

While unemployed in 1977, Yronwode created a magico-religious index to the comic called the Lesser Book of the Vishanti; she later published parts of it in various small presses and it is posted on her website in updated form.

Titles included Modesty Blaise by Peter O'Donnell and Jim Holdaway, Mike Hammer by Mickey Spillane, and The Phantom by Lee Falk.

[12] Similarly, when Dan Brereton received a poor review from Yronwode for an early project, he felt his "promising career in comics was over.

"[13] The column, and her work with the APA-I comic-book indexing cooperative, led to freelance editing jobs at Kitchen Sink Press.

[14][15] While working at Eisner's archives in December 1981, she met Dean Mullaney, the co-founder of Eclipse Enterprises, a graphic novel publisher.

[17] Eclipse's output rapidly grew, and by the mid-1980s they were the third-largest company in the American comics industry, despite only selling their titles via the direct market.

[18] Through a mixture of a booming industry, a growing creator-owned movement, Dean Mullaney's business acumen, and Yronwode's intricate knowledge of the market, the company published numerous award-winning titles, including Scott McCloud's Zot!, Mark Evanier's The DNAgents and Alan Moore's Miracleman, as well as importing numerous titles from the United Kingdom and Japan for the American market.

[21][22][23] Yronwode was writing another non-fiction book, a biography of Steve Ditko, but the work was lost when Eclipse's offices were flooded in February 1986.

[24] Yronwode covered the events - which included herself and Mullaney losing most of their possessions when their house also flooded - in Fit to Print and Penumbra columns.

[26] With the comic market contracting in the late 1980s, Eclipse developed a new line of non-fiction, non-sports trading cards, edited by Yronwode.

She is the co-proprietor, with her husband Nagasiva Yronwode, of the Lucky Mojo Curio Company, an occult shop, spiritual supply manufactory, book publishing firm, and internet radio network for which she writes, edits, and produces graphic label art.

She is on the board of the Yronwode Institution for the Preservation and Popularization of Indigenous Ethnomagicology (YIPPIE), a 501(c)3 not-for-profit foundation that archives the material culture of 19th and 20th century folk magic and divination.

Under the imprints of the Lucky Mojo Curio Company, Missionary Independent Spiritual Church, and YIPPIE, the Yronwodes edit and publish books by a variety of other authors as well as their own works.
