Dousman's father had also had prominent connections in St. Louis. Dousman readily entered its uppermost social circles. He began a career as an art collector, amassing a collection of nearly a hundred paintings, mostly Academic art from France. In 1879, he constructed a gallery adjoining his St. Louis home to showcase his collection and began opening the gallery to the public. His art collection was eventually published in 1881. Dousman received much attention in both St. Louis and other major cities across the nation for his collection. He served as art director for three years for the St. Louis Fair.
