Dougherty became an assayer and chemist 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. After that he worked for the American Steel Foundries Company as the Head Chemist 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.

Dougherty created a formula to figure out how much nickel was in armor 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. 

 

He also figured out a way to figure out how much vanadium was in steel.  This is important because vanadium is used to make car axles.    He also studied the amount of salt in petroleum

He encouraged deaf students to go to college and become professionals.  He was one of the founders of the National Association of the Deaf.  He was also a leader at the World Congress of the Deaf and Chicagoís 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 education and worked to preserve American Sign Language.  He gave a lecture in sign language about the discovery of chloroform in 1913 and it is still saved at the Library of Congress.
