John Albert Ewell earned a B.A. in Chemistry (Morehouse College-1948), and was a graduate student in Physical-Chemistry (University of Colorado,1949-51). He earned, from the University of California at Los Angeles, an M.S. (1955) and a Ph.D. (1966) in Mathematics. From 1955 to 1970, he held the position of Assistant Professor of Mathematics at Southern University, California State University Long Beach, and York University Ontario, Canada. In 1970, Dr. Ewell became Associate Professor at California State University Sonoma. From 1973 to 1998 he taught at Northern Illinois University from which he retired as Professor Emeritus August 15, 1998.

From 1968 until retirement in 1998, John Albert Ewell III published 43 papers in Mathematics. He has published 4 papers since retiring. In June 2003 Dr. Ewell gave a lectre on his research at CAARMS 9.
