Edwin Hubble's 1929 observation that galaxies were generally
receding from us...
It was V. M. Slipher who provided the radial velocities, though
Hubble is often incorrectly given credit. What Hubble actually
provided were the galaxy _distances_. (The web page cited is correct
if you read it carefully.) By plotting velocity against distance,
Hubble discovered that recession speed is proportional to distance.
I agree.
