Mathematician Raymond L. Johnson was born on June 25, 1943 in Alice, Texas, a small town near Corpus Christi. He was raised by his mother Johnnie Johnson, his maternal grandmother Ethel Pleasant Johnson, and her second husband Benjamin Thompson. Growing up, it was Benjamin Thompson who taught Johnson how to read and do some arithmetic. This sparked an early interest in mathematics and allowed Johnson to skip the first two grades. Johnson attended a two room schoolhouse because the nearby grade school was segregated. With the help of his mentors, Larry O’Rear and Stan Brooks, Johnson excelled in high school mathematics. He went on to major in mathematics and received his B.A. degree from the University of Texas in 1963. Link: http://www.thehistorymakers.com/biography/raymond-johnson
