Louis M. (Louis Marcus) Roth

Born in 1918, Louis M. Roth was an American entomologist best known for his long scientific career studying cockroaches. He published extensively on their reproduction, classification, and biology, and co-authored important early work on the medical and veterinary importance of cockroaches as well as their role as household pests.

Much of his research focused on the details of insect life that most people never notice: how cockroaches develop, how different species are related, and how they adapt so successfully to human environments. That careful, long-term work made him a respected specialist in his field, especially among researchers interested in insect systematics and urban pests.

Although biographical information about him is limited in the sources I could confirm, his scientific legacy is clear. Across many papers and monographs, he helped build the foundation for how scientists describe and understand one of the world’s most persistent groups of insects.
