Who is credited with developing early embalming methods through the injection of fluids?

Jean N. Gannal is credited with developing early embalming methods through the injection of fluids. He was a French surgeon and the author of the first book on the subject of embalming in the 19th century, titled "History of Embalming." This work laid the groundwork for modern embalming practices by providing detailed descriptions of the techniques used for preserving human remains, including arterial embalming, which involves injecting embalming fluid directly into the circulatory system.

Gannal's contributions significantly advanced the field of embalming, emphasizing the importance of using chemicals to delay decomposition and preserve the appearance of the deceased. His methods reflected a shift in attitudes toward death and the care of the body, moving towards more systematic and scientific approaches to embalming.

In contrast, the other individuals listed, while important figures in the history of medicine and embalming, did not specifically develop early embalming methods through the same innovative techniques as Gannal did. Dr. William Harvey, for instance, is known for his work in physiology and the circulation of blood, and Richard Harlan was noted for introducing embalming to America but did not pioneer the methods themselves. J. Anthony Gaussardia is not widely recognized in the context of early embalming practices
