James Lequeux completed his PhD thesis in radioastronomy in 1962 and was an assistant, then associate, professor of physics and astronomy at Paris University until 1966. He was an Astronomer from 1966-1999 and an invited scientist at CalTech from 1968-1969. Dr. Lequeux was also the Director of the Marseilles Observatory from 1983-1988 and was Editor-in-Chief of the journal Astronomy & Astrophysics for 15 years. He retired in 1999 and then began work on the history of astronomy, a subject he presently writes about. Dr. Lequeux has published over 403 papers and five books, including The Interstellar Medium (Springer 2005) and Le Verrier: Magnificent and Detestable Astronomer (Springer 2013).

"Francois Arago is a fine, scholarly work, fully footnoted, with a detailed bibliography. The layout and exposition are clear, making it easy to locate specific researches. It is very well written and easy to read. I thoroughly enjoyed this book and learned much from it, and warmly recommend it to everyone interested in early-19th-Century astronomy and physics."
