As an undergraduate attending Quincy University in Illinois, gh co-founder Dave Schleppenbach, met his wife, Wendi. Blind since birth, Wendi became an inspiration to Dave as he learned of the obstacles and frustrations blind people face every day. In 1995, Dave formed the VISIONS Lab (Visually Impaired Students Initiative ON Science) at Purdue University, and with his partner, Joe Said, the pair of inventors set out to design new technologies to aid the visually impaired students at Purdue in their struggle to learn.
As the VISIONS Lab grew in demand, Dave and Joe began to set their goals higher and wanted to make their technologies accessible to all visually impaired people. With the aid of the Purdue Research Park and the assistance of the Purdue Gateways Program, Dave and Joe founded gh, LLC in February of 2000.
