Goddard proposed liquid propellants about fifteen years earlier and began to seriously experiment with them in 1921. The German-Romanian [[Hermann Oberth]] published a book in 1923 suggesting the use of liquid propellants.<ref>{{Cite web |title=Hermann Julius Oberth |url=https://pioneersofflight.si.edu/content/hermann-julius-oberth |access-date=2024-11-16 |website=pioneersofflight.si.edu |language=en}}</ref>
