Vesto Melvin Slipher ( / ˈslaɪfər /; November 11, 1875 – November 8, 1969) was an American astronomer who performed the first measurements of radial velocities for galaxies. He was the first to discover that distant galaxies are redshifted, thus providing the first empirical basis for the expansion of the universe.
Vesto Slipher (born November 11, 1875, near Mulberry, Indiana, U.S.—died November 8, 1969, Flagstaff, Arizona) was an American astronomer whose systematic observations (1912–25) of the extraordinary radial velocities of spiral galaxies provided the first evidence supporting the expanding-universe theory.

Vesto Melvin Slipher was a pioneer of spectroscopic astronomy who discovered the radial velocities of spiral nebulae and the rotation of planets. He also directed the Lowell Observatory and received several awards, including the Bruce Medal in 1935.
Vesto Melvin Slipher (1875 - 1969) History. This page is motivated by a feeling I have held for some years: that a very large share of the credit for the discovery of the expanding universe is due to Slipher, and yet he tends to take very much second place to Hubble in most accounts.
