David G. Hartwell died today. He was 74.
For those of you who haven't heard of him, two factoids might be of interest. Firstly, he was nominated for a Hugo award on 39 occasions (winning three times). That fact alone probably says more about his standing within the SF field than anything I can add. (Patrick Nielsen Hayden, Tor's Editorial Director, describes him as "our field's most consequential editor since John W. Campbell.")
Secondly, he acquired and edited my Merchant Princes for Tor; and acquired and was editing a new trilogy in that setting for publication next year. I've known him for more than 15 years and was looking forward to seeing him again next month—this is a terrible shock.
A giant of the field has departed, and I'm going to miss him as a friend as well as an editor. I offer my deepest sympathy to everyone else who knew him.
