Tracing the Tricentennial highlights key events in the lives of the residents of the Hermann-Grima and Gallier Houses and those relating to the construction of and changes in ownership of the houses. This timeline places them in the larger context of New Orleans’ 300-year history, using images from our collection, and from other institutions. Such issues as immigration, slavery, the Civil War, economic strife, and yellow fever had lasting implications for the Hermanns, Grimas, Galliers, and the people they enslaved.
