In Winslow's 40th anniversary address, he described Dunham as one of New York City's elite, "wise counselor to many."
Dunham worked closely with Biggs during the cholera scare in 1892, and his descriptions of the cases represented the most modern methods of the day. At the Carnegie, Dunham extended Prudden and Park's studies on electrolyzed sea water to determine its effect on the Spirillum asiaticae, and with Beebe and Biggs, evaluated the effectiveness of sulfurous acid gas as a disinfectant.
At the 1902 SAB meeting, he presented on "The Influence of Physical Conditions on the Character of Colonies on Gelatin Plates: A Preliminary Communication," in which he describes the profound influence in the "stiffness" of gelatin. He concludes, that "the physical properties of gelatin and temperature of incubation should receive fully as much attention as the ingredients and reaction in the standardization and use of gelatin, particularly when employed for plating with reference to species." The paper was discussed by Sedgwick and Conn.
