ON March 8, the Rumford Premium of the American Academy of Arts and Sciences was presented to Charles H. Townes, professor of physics at Columbia University, for his origination of the maser.

At the present time an award of five thousand dollars accompanies the medals. Count Rumford also stipulated that the recipient should be “the author of the most important discovery or useful improvement…on Heat or on Light….”
