First awarded in 1937, the Roebling Medal is the Society's highest honor. It is given in recognition of an individual's lifetime scientific eminence as represented primarily by publication of outstanding original research in mineralogy. The recipient is made a life fellow of the Society and receives a gold medal engraved with their name and the resemblance of Washington A. Roebling. Washington Roebling was Chief Engineer during construction of the Brooklyn Bridge, a mineral collector, and a significant friend of the Society in its early years. Roebling gave the society a gift of $40,000 in bonds which became the Roebling Fund and has grown to over $1.5 million.
