The Henry Draper Medal is awarded every 4 years by the United States National Academy of Sciences "for investigations in astronomical physics".<ref name="nas">Template:Cite book</ref><ref name=henrydrapermedal-1>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Named after Henry Draper, the medal is awarded with a gift of USD $15,000.<ref name="nasa">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> The medal was established under the Draper Fund by his widow, Anna Draper, in honor of her husband,<ref name="acad05">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> and was first awarded in 1886 to Samuel Pierpont Langley "for numerous investigations of a high order of merit in solar physics, and especially in the domain of radiant energy".<ref name="sciam" /> It has since been awarded 45 times.
The medal has been awarded to multiple individuals in the same year: in 1977 it was awarded to Arno Allan Penzias and Robert Woodrow Wilson "for their discovery of the cosmic microwave radiation (a remnant of the very early universe), and their leading role in the discovery of interstellar molecules";<ref name="npw1140">Template:Cite book</ref><ref name="az232">Template:Cite book</ref> in 1989 to Riccardo Giovanelli and Martha P.

Paul Butler and Geoffrey Marcy "for their pioneering investigations of planets orbiting other stars via high-precision radial velocities".<ref name="maetu152">Template:Cite book</ref>
