The Jerome C Hunsaker Visiting Professor of Aerospace Systems Department of Aeronautical and Astronautical Engineering, Massachusetts Institute of Technology BIOGRAPHY Dr. Leopold had led the Arizona-based licensing and technology transfer business for Motorola Corporate Technology when he retired in 2003. He had previously served as the Chief Technology Officer(CTO) for the Global Telecom Solutions Sector($6B sales and 20,000 people in 2001), and prior to that assignment had served as the Cto for the Satellite Communications Group($1B sales and 3, 500 people in 1998). He is one of the three engineers who created the Iridium( System, the first realization of global, wireless, personal communications. The Iridium System integrates a packet-switched architecture within its globally deployed constellation of satellites together with the circuit-switched architecture of the public-switched telephone network. ( Today, Iridium Satellite LLC, Loudin County, Virginia, operates the Iridium System. He is known throughout the world for having presented keynote addresses and technical papers in many international forums, and for engaging in telecom regulatory activities.
