23877 Gourmaud           Discovered 1998 Sept. 16 by the OCA-DLR Asteroid Survey at Caussols.
Jamy Gourmaud (b. 1964) is a journalist involved with Frédéric Courant and Sabine Quindou in the creation of the French television science program c'est pas sorcier. With the help of scale models, Gourmaud explains the concepts behind the facts. Thousands of different scale models have been built and used in the program.
