Dr. Henry Pym
Dr. Henry Pym is a noted biochemist and member of the Tesla Club, a fraternal organization of scientists. Currently, his reputation in the academic community is on shaky ground, after his controversial "discovery" of "Pym Particles", which he claimed were subatomic particles which could alter the size of atoms. In reality, his samples were forms of an aerosolized corticosteroid, which induced short-lived cellular growth in organic subjects. While his research was valid, it was his misrepresentation of that research which cost him his standing in the community.
In March 2004, Dr. Pym attempted to woo Dr. Moira MacTaggart, almost refusing to take no for an answer until a well-timed intervention by Nathan Dayspring convinced the would-be suitor to direct his attentions elsewhere. Shortly thereafter, Dr. Pym's legal troubles took hold and he has not made any public appearances since.
