Who authored the Book of History of Embalming?

The Book of History of Embalming was authored by Jean Gannal, making it a significant contribution to the field of embalming. Gannal's work is important because it not only covers the techniques of embalming but also provides a historical perspective on its practices, highlighting the evolution of methods and beliefs over time. His thorough research and documentation helped establish a more scientific understanding of embalming, which is fundamental for anyone studying funeral service practices.

The other individuals listed are notable in their own fields but are not relevant to the history of embalming in the same way Gannal is. Harlan, while involved in related practices, did not author this particular work. Anthony Van Leeuwenhoek is known for his contributions to microscopy and biological sciences, and William Harvey is renowned for discovering the circulation of blood. Their contributions do not intersect with the specific topic of embalming history. Thus, Jean Gannal stands out as the key figure for this inquiry.
