Jim had a stroke two weeks ago, one that was characterized as "serious." At the time, the people he worked with explained that there were "very detailed emergency plans" left in place by Jim.
Here's author David Drake's obit for Jim.
James Patrick Baen was born October 22, 1943, on the Pennsylvania-New York border, a long way by road or in culture from New York City. He was introduced to SF early through the magazines in a step-uncle's attic, including the November, 1957, issue of Astounding with The Gentle Earth by Christopher Anvil.Link (Thanks, David!)
The two books Jim most remembered as being formative influences were Fire-Hunter by Jim Kjelgaard and Against the Fall of Night by Arthur C Clarke. The theme of both short novels is that a youth from a decaying culture escapes the trap of accepted wisdom and saves his people despite themselves. This is a fair description of Jim's life in SF: he was always his own man, always a maverick, and very often brilliantly successful because he didn't listen to what other people thought.
For example, the traditional model of electronic publishing required that the works be encrypted. Jim thought that just made it hard for people to read books, the worst mistake a publisher could make. His e-texts were clear and in a variety of common formats.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
