Dijkstra had a lot of influence for some years on the UTCS undergraduate program, whose first undergraduate course for much of the 1990s was taught in Haskell and was a brutal weed out, at ~70% attrition for the first year courses.
The UTCS undergrad program has been "nerfed" twice since the 1990s - in 2001 and in in 2014. Various political interests during the first tech bubble - to produce more graduates - and later, to have more under-represented minorities, have dramatically reduced what Dijkstra pushed for.
However, by 2001, the failure rate was so high that the department moved to Java, much to Dijkstra's chagrin: https://chrisdone.com/posts/dijkstra-haskell-java/
