David B. Eisenhaure, 75

David B. Eisenhaure died on Oct. 16. He was 75.

He is survived by his wife of 51 years, Mary Eisenhaure, of Cohasset; his daughter, Rachel Eisenhaure, and her husband, Ken Clark, of Weymouth; and grandchildren Owen, Agatha, Margaret, and David Clark. He is also survived by his siblings, Ward Eisenhaure, of Hingham, and his wife, Barbara; and Jane O’Brien, of Lincoln, and her husband, Mike. He was the proud uncle of Reid and Jeanne Eisenhaure and Edward and Michael O’Brien.

Growing up on a farm in North Reading provided David with a hands-on education in both nature and machines. He studied mechanical engineering and played rugby at MIT, meeting his future wife during his senior year. As an MIT graduate student, he worked on attitude control systems for NASA’s Apollo missions. In his spare time, he became an award-winning striped bass fisherman.

Following completion of his MIT graduate studies, David worked at Draper Laboratories in Cambridge until 1985, when he left to found his own company, SatCon Technology Corp.

SatCon developed groundbreaking technology in energy storage and other areas, going public on Nasdaq in 1992. After SatCon became public, it acquired nine companies, including Westinghouse’s R&D laboratory, from Northrup Grumman, creating a diverse organization with four plants in the United States and Canada. SatCon provided products and services to major international companies, including Chrysler, General Motors, Ford, Litton, Applied Materials, as well as major divisions of the U.S. armed forces. Products developed by SatCon have contributed to the advancement of the utility, hybrid vehicle, ship building, industrial automation, semiconductor processing, and defense markets. SatCon is particularly well known for its work in advanced electric drives, in the technology of inverters for smart grid and photovoltaic applications, and in the development of light-weight, high-power electronics, which contributed to the development of practical hybrid and electric vehicles.

In addition to his work on SatCon, David served on the board of directors of a number of publicly traded companies and participated on the National Council for Technology Innovation from 1998-2005. After retiring from SatCon, he continued to invent through the end of his life, developing designs for the smooth integration of renewables into the electrical grid.

David loved fitness, being an avid weightlifter, and he loved the outdoors.
