Le Petit Saint-Louis' town house

This is the house where Pierre Méchain, a future scientist, was born in 1756. He was famous for a number of reasons, including measuring the length of the earth's meridian as part of a geodesic mission ordered by Louis XVI.

But he is also known for his immense work as an astronomer, with no fewer than 7 comets discovered by him.
Since 1999, an asteroid has been named in his memory: (21785) Méchain, no mean feat!
A secondary school in the lower town of Laon also bears his name...
