**William Charles Brenke** (April 12, 1874, Berlin – 1964)^{[1]} was an American mathematician who introduced Brenke polynomials and wrote several undergraduate textbooks.

He received his PhD in mathematics at Harvard under Maxime Bôcher. Brenke taught at the University of Nebraska-Lincoln mathematics department from 1908 to 1944 and was chair of the department from 1934 to 1944. He retired in 1943 but his successor, Ralph Hull, was put on official leave to do war work and returned from leave in 1945.^{[2]}
