In 1965, he was a cofounder of Cruizin 4', Syndikat für Kunstbetrieb, together with fellow artists Francesco Mariotti, Hermann Prigann, Werner Nöfer and Dieter Glasmacher. It is best known through two events: The opening of the exhibition Cruizin 4 in the Gallery Mensch at Fischmarkt Hamburg-Altona, where the members came with a stretched limousine with chauffeur. And by a performance at Cosinus, a legendary pub in the university district. The Happening1. World Record in Permanent Painting took place under medical, and specifically psychiatric care, too, by doctors of the University Hospital Eppendorf.. Under the moniker Dizi, Dirk Zimmer had a brief career as a painter during the German avant-garde movement and then turned to filmmaking, which he eventually dropped in the late 1970s to work as an illustrator for such American publications as Crawdaddy, the New York Times, and The New-York Magazine. Over the years, both his paintings and illustrations, were shown in private galleries in New York, Germany, Switzerland, and France.
The American period
His work as a children's book illustrator began after moving permanently to New York City in 1977. He also continued to exhibit his artwork and to be a presence in the New York art scene. He found a flat in John Street, right under the roof, for a lengthy period of time. The only media contact to his homeland was through the German Boa Vista magazine, in which he first published vignettes, than later his written and illustrated short-story comic with the cryptically and untranslatable German title Die mysteriöse Schratzmichlöse. From 1978 to 2004 Zimmer published more than two and a half dozen kid's books. Zimmer moved to Barrytown, NY in the early 1980s, and later lived in the Rondout area of Kingston. He was a contributor and collaborator at the northern Dutchess quarterly AboutTown. He later moved to Tivoli, NY. In 1990, he was one of a small group of illustrators—including Natalie Babbitt, Maurice Sendak, Marc Simont and Barbara Cooney—whose work was featured in The Big Book for Peace, an anthology of 34 artists and writers.
In Tivoli, on a walk to the river on the afternoon of September 21, 2008, Zimmer was struck by a car. He died five days later on September 26 from his wounds at St. Francis Hospital in Poughkeepsie, N.Y. He is survived by two sisters who live in Germany. The sequel of the book Egon, on which he was working at that time, was left unfinished. Egon, Zimmer’s adventurous, furry alter ego, leaves the following note at the end of the book: "I am having a good time. I will be home some day but not until the show ends. Maybe soon."
Zimmer's offbeat, sometimes grotesque, but always gentle humor made him one of the most sought-after illustrators for "scary" picture books, two of which were selected as American Library Association Notable Book lists for children's books. The Trick-Or-Treat Trap—the only book that he has written and illustrated by himself, got the most resonance and response in criticism. So The New York Times praised the humor of this work with the adjective "tongue-in-cheek": "His pen has bite as he pictures a wonderfully wicked assortment of ornery little beings."
