That's what's funny about the whole thing; Heisenberg mistakenly thought his own equation was due to the observer effect. There's a good article on him almost failing his PhD exam because he had difficulty with a related concept (https://www.aps.org/publications/apsnews/199801/heisenberg.cfm https://www.aps.org/publications/apsnews/199801/heisenberg.c...). It's amusing because he was later awarded the Nobel prize for "the creation of quantum mechanics".
