Who was the first to make embalming widely available to the public?

The correct answer is Gannal, who is recognized for making embalming widely accessible to the public. His contributions in the early 19th century were significant as he published the first comprehensive work on embalming techniques, titled "History of Embalming," in 1850. Gannal's methods helped disseminate knowledge and practice of embalming beyond a limited scope, allowing for greater public awareness and acceptance of the process. His influence extended throughout Europe and into the United States, establishing a foundation for modern embalming practices and broadening the funerary profession.

In contrast, the other individuals mentioned played various roles in the development of funeral service practices, but none achieved the same level of impact in publicizing and standardizing embalming techniques as Gannal did. Understanding this context helps highlight Gannal's key role in the history of funeral service education and practice.
