Formerly a lurker on soc.history.what-if, Neopeius moved to alternatehistory.com some time in the mid 2000s. He was a long-time lurker there, too, until he decided to give back to the community with his ongoing timeline.
Sputniks - His major timeline on AH.com, about alternate developments during the Space Race of the 1950s and 1960s.
Neopeius is a published space historian and member of the American Astronautical Society History Committee. He maintains a website devoted to the Space Technology Laboratories-managed space shots from 1957-1961 (Pioneers 0-2, Explorer 6, Atlas Able, Pioneer 5) at The on-line STL Archive
Along with truth_is_life and e_of_pi, he makes up the triumvirate of AH space authorities, who will generally make an appearance in any AH space-focused thread.
Neopeius will read each and every thread in which France beats or has a chance of beating Germany in World War 2.
