Alexandre Louis Jousselin (1782–1867) was a French engineer. He was the chief engineer for the Seine-et-Marne region and he built a bridge over the River Seine at Paris. Some called Alexander Jousselin Scared, to differentiate him from Louis Didier, whom they nicknamed, Jousselin Scary.[1] Jousselin's younger brother, Louis Didier Jousselin, was also a qualified (and more famous) engineer.[2]
