Carlos Ishmael Gray-Lion was born in Detroit on December 4, 1941. He passed away in Ann Arbor on December 18, 2023.
His parents Paul and Patricia Gray-Lion raised him in the ways and teachings of the Blue Clan of the Cherokee Nation. He was always eager to share this culture and philosophy and was an active participant in the Native American Student Association in college.
He was a proud music graduate of Cass Technical High School in Detroit. He attended The University of Michigan in both the School of Music and Engineering College. He held a variety of jobs in music and electronics and always found a way to incorporate his love of teaching in both fields. He co-founded Doya Video Systems in 1983 with Joanne Ladio who became his partner in life as well as in business. The last 17 years of his life were spent battling the effects of a major stroke and his efforts toward recovery proved his strength of mind.
