Born in West Lafayette Indiana in 1963, Federspiel earned a PhD in experimental nuclear physics from the University of Illinois at Urbana–Champaign in 1991, where he led the first self-consistent measurement of the electric and magnetic polarizability of the proton. In 1993, he married his wife, Carey Mills, who bore him four children, Erin, Harry, Ella, and Leo. A Baritone Sax enthusiast, he played in professor John Garvey’s Jazz band for seven years. In 1991 Federspiel joined Los Alamos National Laboratory where he built the real-time data acquisition and analysis system for the Liquid Scintillator Neutrino Detector experiment, which reported evidence for neutrino oscillations in 1996. In 1997 he joined BiosGroup, and then in 1999 founded e-Xchange Advantage Corporation to deploy technology allowing institutional traders to control the information released to the market about their orders. e-XA became Pipeline Trading Systems LLC, which implemented Federspiel's inventions to reduce the cost inflicted by high-frequency trading on institutional trade execution. Federspiel's block market invention was one of two major market structure experiments enabling institutions to direct information dissemination about block orders to likely trading counterparties, the other notable example being Liquidnet. In 2011, Pipeline reached a settlement with the Securities and Exchange Commission over allegations that a Pipeline affiliate may have traded with Pipeline customer orders without adequate disclosure. Federspiel agreed to pay the SEC $100,000 to settle the matter. Federspiel is currently CEO and Founder of DartVideo Communications, provider of Home Dart, a real-time video text messaging tool for real estate professionals.
