About the author

Edgar George Thomssen was an American technical writer and author born in 1886. He is chiefly associated with hands-on books about soap-making, detergents, and cosmetic manufacturing, written for readers who wanted practical instruction rather than theory alone.

His best-known title is Soap-Making Manual, a detailed guide to raw materials, production methods, analysis, and quality control in the modern soap plant. Library and public-domain records also connect him with later work on soaps and detergents, showing a sustained focus on applied industrial chemistry.

Reliable biographical detail about his personal life appears to be limited in the sources available here, so this overview stays close to what can be confirmed from book and library records. Even so, his surviving books make his specialty clear: explaining the making of everyday products in a direct, useful way for working readers.
