On January 20, 2016, we lost David Hartwell, a longtime friend of SFRA. In 1999 David won SFRA's Clareson award, which recognizes service to the field. It is difficult to imagine anyone more deserving, as David was an important figure in science fiction publishing and criticism.
To me David was unfailingly generous, and I will miss his encyclopedic knowledge, keen insight, good humor, and kindness.
