I started going to Horror, Fantasy and sci-fi conventions two decades ago, and every time I went, Charles Brown, the founding editor of Locus, was there. He was everywhere and knew everyone. I guess I thought he'd be there forever, because I was certainly a bit shocked to learn that he had died.
When I read his obit, I was even more impressed. He had started Locus as a means to secure Boston as the site of the annual World Science Fiction convention and then continued publishing it, turning it into a major voice for a genre. As someone who has started her own share of niche publications, that was quite a feat.
He'll be missed.
