About the author

Born in 1886, Edgar George Thomssen wrote practical books on soap manufacture and related chemical processes. Records for his books consistently identify him as the author of Soap-Making Manual (published in 1922), a handbook that set out to explain raw materials, production methods, analysis, and plant control in straightforward language for people working in the trade.

His later work shows a continued focus on the same field. Library catalogs also list Modern Soap Making from 1937, co-authored with Clarence Ralph Kemp, and Soaps and Detergents from 1949, co-authored with John W. McCutcheon, suggesting a long-running role as a specialist writer in industrial soap and detergent technology.

Reliable biographical detail beyond his birth year is limited in the sources I could confirm, so it is safest to remember him primarily as a clear, practical author whose books served manufacturers, technicians, and serious learners interested in the chemistry and craft of soapmaking.
