Haiblum, Isidore
Entry updated 21 April 2025. Tagged: Author.

(1935-2012) US author, born, educated and based in New York, where he set much of his fiction. Haiblum's best work can best be described as Judeofuturism, a term for which he must be considered an obvious early influence in the same sense as, say, Samuel R Delany's influence on Cyberpunk. The bulk of Haiblum's work combines a tongue-in-cheek hardboiled narrative with a distinctly Yiddish Humour sensibility. His first and most significant novel was The Tsaddik of the Seven Wonders (1971), which while little appreciated on publication it became a kind of rallying point for Israeli sf/fantasy writers who encountered it in Hebrew translation; its influence can be felt on the works of both Lavie Tidhar and Nir Yaniv. The novel concerns an intergalactic operative caught in a complex Time Loop that runs through Jewish history – "Because Jews are everywhere", as the Tsaddik of the title explains. It is a novel to be experienced as much as read, and has remained, if not a sole example then a very rare one, of purely Jewish sf.
Later works continued to mix hardboiled and humour to varying effect, as in The Wilk Are Among Us (1975; rev 1979) with its amusingly overcomplicated plot, its frenetic spoofing of the Aliens-in-our-midst theme, and its general failure to take hold of its materials. Nightmare Express (1979), a comparatively ambitious Alternate-History detective novel, and the later Mutants mystery series set in the twenty-first century – The Mutants Are Coming (1984) and Out of Sync (1990) – maintain a similar tone. After at least two extremely loose sf series featuring detectives – the Gunjer books beginning with Interworld (1977) and the Siscoe and Block books beginning with The Identity Plunderers (1984) – Haiblum began to publish non-fantastic detective novels, of which the Weiss and Weiss sequence is of significant interest for its near-wholesale invention of Yiddish Hardboiled, but remains outside the scope of this encyclopedia.
