Steven Todd Kirsch is an American serial entrepreneur who has started seven companies: Mouse Systems, Frame Technology Corp., Infoseek, Propel, Abaca, OneID, and CoinTrust. Kirsch's most recent venture, CoinTrust, focuses on mainstream adoption and security of cryptocurrencies, such as Bitcoin. He invented and owns a patent on an early version of the optical mouse. In 2007, his personal fortune was estimated at $230 million, the majority earned from the IPO of Infoseek and the acquisition of Frame Technology. He has a Bachelor of Science and a Master of Science in electrical engineering and computer science from the Massachusetts Institute of Technology. He used part of his fortune to set up a $75M charitable fund and became an philanthropist. On August 11, 2007, Kirsch announced on his personal Web site that he had been diagnosed with Waldenstrom's macroglobulinemia, a rare blood cancer. His cancer is shrinking as a result of treatment using an experimental HDAC inhibitor, LBH-589. In 2003, Hillary Clinton presented Kirsch with a National Caring Award from the Caring Institute in Washington DC.
