Henry worked with his father in the design and construction of steam powered pumps to help de-salt the water for New Orleans, Louisiana. He died there of Yellow Fever while involved in the waterworks project. His father also died from Yellow Fever in New Orleans three years later while engaged in the same work.1552

My father had a contract for supplying the City of New Orleans with water, and had sent my half brother, Henry, there to look after the work. While we lived in Speaks' house, news came to my father of his death. It was a heavy blow to him.

Henry was a brave, gallant fellow who had distinguished himself at the battle of New Orleans on the 23rd of December, was accomplished for his years, had become an able architect, and was universally esteemed. My father felt his loss, not only in the death of a son, but in the confusion caused by it in connection with the contract.

I remember the death and the gloom and the mourning. But I had rarely seen my brother, and to me the loss was a slight affliction.1610
