JAMES MATHER (“JIM”) SPRAGUE, THE Joseph Leidy Emeritus Professor of Cell and Developmental Biology at the University of Pennsylvania died from leukemia on December 22, 2002, at the age of 86.

Jim Sprague was one of the pioneers in the study of the anatomy, physiology, and functions of the brain, and he was a member of the Founding Council of the Society for Neuroscience in 1970. He was elected to membership in the National Academy of Sciences in 1984.

He fell in love with the prospect of becoming a naturalist, and this interest helped him to develop the sort of wide-ranging, questioning mind that matured into the successful neuroscientist that Jim became.

He “tramped” the Missouri River bottoms,
