This timeline was a component of the exhibit An Architect and His City: Henry Howard’s New Orleans, 1837–1884. When Howard arrived in New Orleans in 1837, the city was the third largest in the United States, but it faced an economic crisis and a yellow fever epidemic. Over the next several decades, Howard’s career was shaped by the events of his city: from the boom of the antebellum years, through the Civil War, to the challenges of Reconstruction and beyond.
