Described by friend, former student, and later professor, H. Lewis Batts:
"In physique Dr. Jameson was tall and stalwart. His movements were energetic and firm. He was energetic in mind also. He had convictions, and by them he was utterly controlled. He was willing to defend them at any time and place. He was particularly effective before public assemblies, being able to convince his hearers by depth of feeling, by sincerity, and by a moral earnestness that would not yield."
