Marla Latham was a teacher hired by R. J. Brande to help train the new recruits of the Legion of Superheroes. He was introduced in Superboy #98 (July, 1962). He also followed his charges on missions as "Adult Advisor" or "Chaperone" under the pretense of being responsible for their security. Actually they took care of themselves and Marla was mostly there to defend Brande from public criticism for endangering minors. He resigned after becoming convinced the Legion had outgrown a need for older mentors. He kept in contact with his former charges either on social occasions or times of need.
