Edmund Kirby Smith
Johnson returned to teaching to become a professor and co-chancellor (1870) of the University of Nashville with former Confederate General Edmund Kirby Smith. His health failing, he retired in 1875 to a farm near Brighton, Illinois, where he died in 1880. He was originally buried in Miles Station, near Brighton, but was reinterred in 1975 to Old City Cemetery, Nashville, Tennessee, to be next to the grave of his wife, Mary.
