David L. Pulver

From the Traveller RPG wiki on wikia.com:

David L. Pulver is a game designer and author based in Kingston, Ontario. Born in Canada, he grew up in England and New Zealand before returning to the Great White North. Traveller was the second role playing game David ever refereed (starting in 1979). His own Traveller campaign lasted 10 years, eventually mutating into a hybrid of GURPS Space and Traveller. He is glad this eminently logical evolution has now been officially recognized as a Good Thing. David's published works includes over two dozen RPG sourcebooks including GURPS Bio-Tech, GURPS Vehicles, Bubblegum Crisis: Before and After (R.Talsorian), Glory of Rome (TSR), and Aliens and Artifacts (ICE).
