About the author

Jacomy-Régnier is known from the 1855 French work Histoire des nombres et de la numération mécanique, a historical study of number systems, mathematical instruments, and early calculating devices.

Surviving online catalog records and digitized editions confirm that this is the principal work associated with the name. The book traces the development of numeration and mechanical calculation from earlier civilizations into the author's own century, showing a strong interest in the history of mathematics and technology.

Very little clearly verified biographical information about Jacomy-Régnier appears to be readily available in the sources consulted, so details such as birth, death, or a fuller career summary are best treated with caution.
