Peter John Desnoyers (August 1, 1772 – June 3, 1846) was a silversmith and businessman, and a leading citizen of early Detroit, Michigan.
The younger Desnoyers set sail to America with other French citizens, arriving in 1790 in Gallipolis, Ohio, where their lands were supposed to be located.
[1] A few of the settlers remained, but Desnoyers moved on to Pittsburgh, and in 1796 accompanied General Anthony Wayne's army to Detroit.
After the fire, Desnoyers rebuilt, this time constructing a building that housed both a general store and silversmithing works.
He served a number of terms as a city alderman, and was director and president of the Bank of Michigan.
