History

The name Saddle is derived from the letters of Scala Data Library. Adam Klein began Saddle development in 2012 while an employee of Novus Partners, Inc. Saddle was open-sourced by Novus under the Apache 2.0 License in 2013. Saddle evolved from earlier prototypes developed by Chris Lewis, Cheng Peng, and David Cru, and draws on Adam's prior experience developing the pandas Python library.
