Hal Clement (Harry Stubbs) was a fixture on the Boskone Program from the first Boskone until his death in 2003 — forty consecutive conventions (and that doesn't count the Boskones he attended in the 1940s). He combined a deep knowledge of science blended with wonder and he combined joy in the learning of it with joy in the teaching of it.
After his death, NESFA decided to honor him by establishing the Hal Clement Science Speaker as a memorial. Each year we bring someone who shares his wide interest in science combined with a love of science fiction to speak at Boskone.
