Ignatz was a science fiction fanzine by Nancy Share.
Ignatz was published beginning in the late 1950s and into the 1970s. It was an 8 1/2 by 11 inch, mimeographed publication, with a dittoed cover.
The first issue was published in December 1952, and was distributed by the Fantasy Amateur Press Association. Issue 5 was released in December 1953, included in the 26th mailing of the Spectator Amateur Press Society, known as SAPS. Number 18 is recorded as appearing October 1958, and no. 19 in January 1959, and both are included in the Fanzine Collection of Temple University Library. It was included in the 101 mailing of the 1972 SAPS.
The title for the fanzine came from the old comic strip Krazy Kat. In the strip Krazy Kat had a sometimes friend - sometimes adversary named Ignatz Mowz, and Ignatz was named for him. Nancy Share popularized the character of Ignatz through her fanzine in the science fiction fandom community of the 1950s, and it became something of a craze.
Nancy Share also published Torrents and was the art director for Fan To See. She had previously co-edited Hodge-Podge with her sister Marie-Louise Share from 1953 till 1955. She later co-edited the zine Churn with Art Rapp (Spacewarp).
