The bitter, public contest for priority over the discovery of the virus that causes AIDS was officially closed in 1987 with equal credit being awarded to two parties from opposite sides of the Atlantic. One was led by Robert C. Gallo of the Laboratory of Tumor Cell Biology at the National Cancer Institute in the United States and the other was led by Luc Montagnier of the viral-oncology unit at the Pasteur Institute in France. Using citation counts from articles published (...) by the scientific community, a process of alloca tion of credit is examined and compared with this official settlement. A novel pattern emerges. It is found that the scientific community began to redistribute priority when the dispute became highly publicized and took little notice of the official settlement. This, along with the fact that Gallo has now officially been charged with misconduct by an investigative committee, may mean that Montagnier's team may eventually receive sole creditfor the discovery of the AIDS virus. The importance of examining priority disputes from many different angles and the potential for citation analysis in such cases are highlighted. (shrink)
