Jérôme Lalande
"ξ Andromedae" (Latinised to "Xi Andromedae") is the star's Bayer designation. It also bears the Flamsteed designation "46 Andromedae". Johann Bayer labeled this star "ξ" in his "Uranometria". The star appeared in John Flamsteed's "Atlas Coelestis", but was unlabeled. It was later designated as "46 And" by Jérôme Lalande. The label "ξ" was used in "Atlas Coelestis", apparently erroneously, for what Bayer had labeled "A" (Bayer's "A Andromedae" has the Flamsteed designation "49 Andromedae").
