I remember Stig Hackvan; I met him a couple of times and I think he might even have visited my house once. I read an obituary for him when he died, but I haven't been able to find it -- first I thought it was here on HN, but it doesn't show up when searching. Maybe it was on a Linux user group mailing list?
