Edwin Eli Starbuck was born on 20 February 1866 in Bridgeport, Indiana, to a Quaker family. Starbuck was educated at Indiana University (BA 1890) where he studied with evolutionist David Starr Jordan; Harvard University (MA 1895) where William James supported his interest in psychology of religion; and Clark University (PhD 1897), where he studied with G. Stanley Hall. In 1896 Starbuck married Anna M. Diller, one of the first Radcliffe women permitted to take courses at Harvard, and took “Diller” for his middle name. He also studied under the educational psychologist Ernst Meumann at the University of Zürich in 1903–1904.
