Established through the Draper Fund by gift of Mrs. Henry Draper. Awarded for "an original investigation in astronomical physics, the results of which shall be made known to the public... The medal is not to be presented...more frequently than once in two years...and the investigation for which it is awarded or completed publication thereof shall have been made since the time of the last preceding award and presentation of said medal." This is interpreted to mean that a major publication resulting from the investigation should have appeared since the last presentation of the award. The medal is awarded every four years and carries with it a $15,000 prize.
Henry Draper was NAS Member, medical doctor, and amateur astronomer. Draper was a pioneer of astrophotography – a specialized type of photography for recording images of astronomical objects and large areas of the night sky. In 1873, Draper resigned from his medical career to focus solely on astronomy. He directed an expedition to photograph the 1874 transit of Venus, and was the first to photograph the Orion Nebula, on September 30, 1880. In addition to this award, a small lunar crater is also named after Henry Draper.
The Henry Draper Medal is the oldest Medal that is presently awarded by the National Academy of Sciences. It was first awarded in 1886 to Samuel P. Langley for “numerous investigations of a high order of merit in solar physics, and especially in the domain of radiant energy.” After receiving this award, Langley went continued to have an amazingly accomplished career in astronomy and aviation. Langley served as the third Secretary of the Smithsonian Institution, where he founded the Smithsonian Astrophysical Observatory. Air and sea craft, facilities, a unit of solar radiation, and an award have been named in Langley's honor.
The most recent Draper Medal was presented to William J. Borucki, space scientist at the NASA Ames Research Laboratory and Science Principal Investigator for the Kepler Mission. Kepler is the first NASA mission capable of finding Earth-size planets in or near the "habitable zone," the region in a planetary system where liquid water can exist on the surface of an orbiting planet.
