However, when the first spectroscopic binary and its orbit were more widely reported, the name connected with it was Pickering. The discovery was announced by Pickering in a presentation to the Philadelphia meeting of the National Academy of Sciences on November 13, 1889. The work was described in a paper "On the Spectrum of Zeta Ursae Majoris," which appeared in the "American Journal of Science" in 1890. In both cases the only mention of Maury was a single line, stating that "a careful study of the results has been made by Miss. A. C. Maury, a niece of Dr. Draper". The sole author credit was given as Pickering.
