From 2004 to 2014, the NSERC André Hamer Postgraduate Prizes were awarded to the most outstanding candidates in NSERC's master's and doctoral scholarship competitions. Valued at $10,000 each, the prizes had been established by Arthur McDonald, winner of the 2003 Gerhard Herzberg Canada Gold Medal for Science and Engineering, in memory of a very promising young scientist who passed away in 2003.
