An American Sequence
To complete the connections, we might consider a few parallels between Heinlein's Future History and Niven's Known Space History.
Heinlein begins with four stories describing technological advances in the second half of the twentieth century. Niven begins with four stories describing interplanetary exploration in the last quarter of the twentieth century.
In the Future History, a period of interplanetary expansion is ended by the Prophets. In the Known Space History, a Golden Age in the Solar System is ended by the kzinti.
In both Histories, there is then an interstellar civilization with FTL travel.
