The Rittenhouse Medal is awarded by the Rittenhouse Astronomical Society for outstanding achievement in the science of Astronomy.
[1] The medal was one of those originally minted to commemorate the Bi-Centenary of the birth of David Rittenhouse on April 8, 1932.
In 1952 the Society decided to establish a silver medal to be awarded to astronomers for noteworthy achievement in astronomical science.
The silver medal is cast from the die (obverse) used for the Bi-Centennial Rittenhouse Medal.
