Dougherty became an assayer and chemist (MP4) at the St. Louis Sugar Refining company. He also worked for other companies such as the Vulcan Steel Works and the Deering Harvester Company. Later he started the National Smelting and Refining Company. His job was to test and study metal (MP4). After that he worked for the American Steel Foundries Company as the Head Chemist (MP4) and Metallurgist. This time it was a permanent job. He was very good at his job. Many other companies offered him a lot of money to work for them. He said no.

Dougherty created a formula (MP4) to figure out how much nickel was in armor (MP4) plate steel. Armor plate steel is used to make armored vehicles for the military. Steel has nickel in it. Nickel keeps the steel from rusting.

Dougherty was active in the Deaf Community. He was the first successful (MP4) deaf scientist to graduate from a state school for the deaf. He proved that deaf people could be just as successful as hearing people.

He encouraged deaf students to go to college and become professionals (MP4). He was one of the founders (MP4) of the National Association of the Deaf. He was also a leader at the World Congress of the Deaf and Chicago's Pas-a-Pas club.

He communicated mostly through writing because he did not think reading lips was accurate. Dougherty wrote many articles. He was a very good writer. One paper he wrote was put into a textbook that many students studied.

He was a supporter of technical (MP4) education and worked to preserve (MP4) American Sign Language. He gave a lecture (MP4) in sign language about the discovery (MP4) of chloroform in 1913 and it is still saved at the Library of Congress.

He died on December 2, 1938.
