J. Maximilian M. Godefroy was a French-American architect. Godefroy was born in France and educated as a geographical/civil engineer. During the French Revolution he fought briefly on the Royalist side. Later, as an anti-Bonaparte activist, he was imprisoned in the fortress of Bellegarde and Château d'If then released about 1805 and allowed to come to the United States, settling in Baltimore, Maryland, where he became an instructor in drawing, art and military science at St. Mary's College, the Sulpician Seminary. By 1808, Godefroy had married Eliza Crawford Anderson, editor of her own periodical, the Observer and the niece of a wealthy Baltimore merchant.
