One series was about a thinking, feeling robot, and one of the stories was titled I, Robot. A few years later, Isaac Asimov would gain even more fame with I, Robot , a book featuring a thinking, feeling robot. Another of Otto's series was about the discovery of mysterious pyramids on other planets. I should point out that Binder was not in the same league as Asimov and Clarke, so I'm not going for any dramatic effect. He had the same skeleton of an idea but the fleshing-out was completely different.
Influences are everywhere, and what matters is the final product.
Almost certainly Clarke and Asimov had read Otto Binder. The writers then were mostly devoted fans who read everything on which they could lay their hands, including most everything published in the genre. At Lunacon, both Clarke and Asimov came over and warmly greeted Otto. One day, the senior counselors took our group to the city in a van. We parked and walked over to the old Cinerama theatre.
