In his honor, the National Association of Mathematicians established the Cox-Talbot Address, which is annually delivered at the NAM's national meetings. The Elbert F. Cox Scholarship Fund, which is used to help black students pursue studies, is named in his honor as well.

 and physics. Cox's brother Avalon was at Indiana University as well; there were three other black students in his class. He received his bachelor's degree in 1917, at a time when the transcript of every black student had the word "COLORED" printed across it.

West Virginia State College

On September 16, 1925, Cox began teaching mathematics and physics at the then all-black, poorly funded West Virginia State College. Professors with a Ph.D. were a rarity there, and his international connections made him stand out as well. He received a salary of $1800. His influence can be seen in the large number of changes in the curriculum between 1925 and 1928. In 1927, he married Beulah Kaufman, the daughter of a former slave. She was a teacher at an elementary school, and worked with Cox' brother Avalon. He and Beulah had met in 1921 and had courted

Howard University

Cox started to teach at Howard University in September 1930. It was very different; despite his high credentials, he was outranked by other professors such as William Bauduit and Charles Syphax. Both had published multiple papers; it was only now that Cox published his graduation paper. Williams, his supervisor, tried to pursue recognition for Cox from a university in another country, but had difficulties in doing so. Different universities in England

 students than any other professor at Howard's University. His students also performed better than those of other professors, and he was a popular professor. Among his students was his son Elbert Lucien Cox. Cox was promoted to Professor in 1947. In 1954 he became head of the department of Mathematics, holding this position until 1961, when he had to quit because he had reached the age of 65. He continued teaching until his retirement in 1966 - three years before his death at age 73 in Washington. Although he did not live to see the first Ph.D. student graduate at Howard, many believe it was mainly due to his contributions that this became possible. Cox' portrait hangs in Howard University's common room.

Family

Elbert and Beulah Kaufman-Cox had four children:
  • James was born on August 9, 1928.
  • Eugene Kaufman was born on September 23, 1930. He is currently an architect.
  • Elbert Lucien was born on January 13, 1933. He followed his father and served as Associate Vice President at Howard University.
  • Kenneth, born January 1935, died at the age of 17 months.

Work

During his life, Cox published two articles. He expanded on the work Niels Nörlund had done on Euler polynomials as a solution to a particular difference equation; in particular, Cox introduced generalised Euler polynomials as a generalisation of Euler polynomials, and the generalised Boole summation formula as an expansion on the Boole summation formula. He also studied a number of specialised polynomials as solutions for certain differential equations. In his other paper, published in 1947, he mathematically compared three systems of grading.
