Vesto Slipher contributions were that he took spectra of the spiral nebulae and discovered galactic redshifts. Slipher discovered that most of the objects were moving away from us at high speeds. As a result of this discovery Hubble correlated Slipher’s measurements with distance. He measured by other means to formulate his law which was that the farther away the galaxy was the Faster it was moving away From us.
