Jérôme Lalande
On 8 July 1798 a large number of spectators gathered in the Parc Monceau to witness the ascent. By all accounts Citoyenne Henri was young and beautiful, and she and Garnerin took several turns around the park to the applause of the crowd before she was assisted into the basket of the balloon by the astronomer, Jérôme Lalande. The balloon trip passed without incident and the journey ended at Goussainville about to the north of Paris.
