Dien Jr., Charles (February 9, 1800 - 1870)

Charles Dien Jr. (February 9, 1800 - 1870) was a French cartographer, astronomer, engineer, and globe maker associated with the observatory of Paris. Dien inherited his map-publishing business from his father, Charles Dien Sr. He is the author of several books and manuals concerning the use of scientific instruments and was a frequent collaborator with Félix Delamarche. Dien was responsible for many improvements in globe making, as described by M. Charles Dupin,

M. Dien has made many improvements upon the paper globes in common use. He has rendered them much less hygrometric; he makes the meridian and the horizon in which the globe moves, of copper. These circles are moveable by means of wheel-work.
