Two years later he earned the Ph.D. in astronomy at Princeton for research on the orbits of binary stars. After a period of illness Russell continued his studies at Kings College, Cambridge University (1902-1904), where he did research at the Cavendish Laboratory. Along with Arthur R. Hinks, Russell developed a method for determining stellar parallax from photographic plates. Their technique enabled astronomers to determine more accurately the distances to far-off stars. In September 1904 Russell, again taken ill, returned to Princeton, where in 1905 he was...
