Slipher	Vesto Melvin Slipher	astronomy	Indiana Univ.		19th century scientist			1901-1916 : Lowell Observatory 1913 : blue-shift observed in Andromeda galaxy (Bull. Lowell Obs., 2, 56) 1914 : first galaxy redshifts observed (Bull. Lowell Obs., 2, 6) 1916-1954 : Director Lowell Observatory 1917 : most galaxies have redshifts (The Observatory, 40, 304) 1925 : red-shifts of galaxies suggest a distance/velocity relationship 1929 : Hubble combines Slipher's redshift measurements with Hubble's distance estimates and postulates Hubble's Law	11 November 1875	1918, PASP 30, 346.. Discussion about the spectra of 'spiral nebula' NGC 4449 and NGC 4214, but no spectra actually published (claims 200 km/s and 300 km/s recession velocities respectively)	Hall, J.S. : 1989, PASP 101, 887. : He discovered the high velocities and rotation of nebulous objects later identified as galaxies. He measured the velocities of 41 of these objects. In 1929 Hubble derived his important velocity-distance relationship using, as he later wrote Slipher, "your velocities and my distances"
