Eugenius Nulty (1790 – July 3, 1871) was an Irish born American mathematician of the 19th century.
After arriving in the United States from his native Ireland, Nulty quickly became ensconced as a member of the new nation's small intelligentsia.
[8] In 1823, the University of Pennsylvania awarded Nulty an honorary A.M.[9] He was elected an Associate Fellow of the American Academy of Arts and Sciences 1832.
[10] Nulty was also a correspondent of mathematician, chemist and natural philosopher Robert M.
Walker, director of the National Institute for the Promotion of Science, called Nulty "unsurpassed at home or abroad" in pure mathematics.
