Who was a key figure in changing public perception of embalming in the 1800s?

The recognition of Allen Durfee as a pivotal figure in transforming public perception of embalming during the 1800s is attributed to his significant contributions to funeral service practices and education. Durfee was instrumental in advancing the techniques of embalming and promoting its use, particularly during the Civil War, when the need to preserve bodies for transportation became evident. His work helped to institutionalize embalming within the funeral profession, leading to increased acceptance among the general public.

Durfee's efforts included teaching and sharing knowledge about the benefits of embalming, which helped to alleviate widespread fears and misconceptions about the process. He played a vital role in establishing standards and raising the professionalism of funeral service, which contributed to changing societal attitudes towards death care practices and the necessity of embalming.
