Albert D. Grauer (b. 1942) is an American astronomer who has obtained time-series and infrared imaging data at international observatories since 1978. He codiscovered the first pulsating central star of a planetary nebula (K1–16). His current interests include photometry of NEAs to determine their physical characteristics.Naming citation (WGSBN Bull. 5, #21, 5), IAU / Minor Planet Center, via NASA/JPL
