Robert Fischell is a physicist, prolific inventor, and holder of more than 200 U.S. and foreign medical patents. His inventions have led to the creation of several biotechnology companies. He worked at the Johns Hopkins University Applied Physics Laboratory full-time for 25 years and part-time for an additional 13 years. He contributed to APL's satellite navigation work; he later developed a rechargeable implantable pacemaker that could be programmed with radiowaves,. He and his team at Hopkins also helped miniaturize the implantable cardiac defibrillator. Mr. Fischell went on to invent the implantable insulin pump, numerous coronary stents used to open clogged arteries, and two feedback systems that provide early warning of epileptic seizures (NeuroPace) and heart attacks. Fischell recently donated $30 million to the University of Maryland College Park Foundation to establish a bioengineering department and an institute for biomedical devices at the A. James Clark School of Engineering.
