 He then took as a partner Charles Soutinger, Fulton’s chief engineer.Under that partnership, Allaire and Stoutinger built the engine for Fulton’s last steamship design, the Chancellor Livingston, as well as the air cylinder for the Savannah, the first steam powered vessel to successfully cross the Atlantic.When Soutinger died shortly thereafter, Allaire removed the business to Corlear’s Hook in lower Manhattan where his brass foundry was located.
