, where he spearheaded the technique of multi-aperture spectroscopy for observing very faint, high redshift galaxies, and was project scientist for several new observing instruments, including an early speckle spectrograph for obtaining spatially resolved spectra at resolutions approaching the diffraction limit. In 1978, along with Augustus Oemler, Jr., he discovered that rich galaxy clusters at large distances (z>0.2) have an excess of galaxies with blue colors when compared to similar nearby low redshift clusters. This is now known as the

Butcher–Oemler Effect The Butcher–Oemler Effect is a scientific hypothesis suggesting the cores of galaxy clusters at intermediate redshift (z ~ 0.3) contain a larger fraction of blue galaxies than do the cores of low redshift clusters. The claim was first put forwa ...
