Did Edwin Hubble ever invent anything else than the Hubble telescope?

Answer 1

Edwin Hubble did not invent the Hubble Space telescope (HST).

Edwin Hubble had been dead for forth years before HST was operational.

HST is named after him. He was an astronomer.

(See related links.)

If anything can be said to be invented by Hubble, it is to be found in a few ideas that came out of a few discoveries he made such as the existence of the Universe.

Only at the turn of the century with the construction of gigantic telescopes of almost a meter in diameter was it possible to distinguish the blobs known as nebulae as being outside of our galaxy. In the 1920s Hubble's observations confirmed the existence of other galaxies in the universe outside of our own galaxy, an idea that existed, but was controversial and lacked evidence earlier. (Earlier, the universe was thought to be infinite, but mostly empty except for our own little neighborhood of a few billion stars in the Milky Way. As always, we were the center of the Universe.)

In the next years, Hubble expanded this with data from others to quantify the observation that the Universe was expanding. (Now called Hubble's Law.) This led, of course, to the first data supporting the Big Bang theory suggested in by Georges Lemaître in 1927.
