Jack Kassewitz is President of Global Heart, Inc., a non-profit organization that he co-founded with his wife, Donna, in 2001. His greatest focus at this time is Global Heart's SpeakDolphin.com - Dolphin Communication Research Project - seeking to significantly expand communication between humans and dolphins.  Jack's passion for this research has propelled him to search out and obtain cutting-edge technology for recording cetaceans in the broadest spectrum and highest definition possible.

A lifelong percussionist, Jack's musical skills led him to thefirst breakthrough in his research - the discovery of complex musical form within dolphin vocalizations.Although the songs within these dolphin vocalizations are too complex for the human ear in their original form, Jack used graduate level musical students from the University of Miami, to perform the dolphin songs on human instruments such as guitar and piano. This allows humans to appreciate the beauty and sophistication of the dolphin composed music.

Recently, Jack's work on the Castaway & Calf Project broke new ground in the field of dolphin communication research. Jack is currently analyzing his recordings of Wilson, Castaway's baby, whom Jack was able to record echolocating even as the baby dolphin was emerging from the womb.
