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.
“V.M.” Slipher was born in Indiana and educated at Indiana University. His entire career was spent at the Lowell Observatory, where he started immediately after receiving his A.B. in 1901 and which he directed from 1916 to 1954.
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.

VESTO MELVIN SLIPHER, a pioneer in the field of astro- nomical spectroscopy during his long career at the Lowell Observatory at Flagstaff, Arizona, probably made more fundamental discoveries than any other observational astronomer of the twentieth century.1 He is best known for his discovery in 1913 of the extraor-dinary radial velocities of the...
