History

The development of the Eureka Streams software began at Lockheed Martin in early 2009. The open source project was first announced publicly at the Enterprise 2.0 Conference in Boston, Massachusetts in July 2009. However, the name "Eureka Streams" was chosen later that summer and subsequently revealed publicly with the open source project announcement on July 26, 2010. The core team behind Eureka Streams resides in the CIO Office of Lockheed Martin Information Systems & Global Solutions. Its principal members include Shawn Dahlen, Chris Keohane, Brian H. Mayo, Steve Terlecki, Blake Caldwell, Chad Scott, Rob Keane, and Anthony Romano. When the open source project was first announced, the open source community initially reacted with some surprise. This is partly because the originating company is a large aerospace & defense company. In addition, the project apparently bucked the trend of fewer enterprises participating in open source projects.
