Origins of the Expanding Universe: 1912-1932

This conference is in honor of Vesto Melvin Slipher and is timed to coincide with the 100th anniversary of the first measured Doppler shift in a Galaxy (then known as a Spiral-Nebula) on September 17, 1912.  We are bringing together astronomers and historians of science to explore the beginnings and trajectories of the subject, at the place where it began.
