Hans took on the 555 timer project after he had already started his own business and did it on contract. The contract helped him survive (with a wife and 4 young kids) while he built his business. I never once heard him comment on disappointment about not getting royalties on the 555 timer, in fact, I never once heard him mention anything about royalties on any of the work he did for other companies during the 60's and early 70's. I don't think it was in the mentality of era. In the time since then, the success and popularity of the 555 timer was enough of a reward for him.
