I'm looking for (names of) philosophers who had successful careers in academia but, for whatever set of reasons, chose to leave and pursue work outside of academia, even if only temporarily.
For this question, please exclude disgruntled PhD students and folks who left academic philosophy due to the work culture/environment or because they did not get tenure-- unless you have an interesting and little-known example. It shouldn't be someone I can find by searching "philosophers who left academia".
Wittgenstein is probably the most famous example. Neurath counts as well due to his work on e.g. Isotype.
I'm primarily looking for contemporary figures. The distinction gets a bit blurry in antiquity because philosophy was a very different beast back then.
