Andrew E. Taslitz, a law professor at Howard University and, most recently, American University, died Feb. 9 at Virginia Hospital Center in Arlington. He was 57.

The cause was cancer, said his wife, Patricia Sun.

Mr. Taslitz, a Reston, Va., resident, joined the Howard faculty in 1989 and became a full professor in 1994. He joined American University’s law school faculty in 2012.

He taught courses in criminal procedure, evidence and criminal law. In 2013, he was named one of the best 26 law professors in the nation in “What the Best Law Teachers Do,” a book published in 2013 by Harvard University Press. He wrote scholarly articles and seven books, including “Rape and the Culture of the Courtroom” in 1999 and “Reconstructing the Fourth Amendment: A History of Search and Seizure, 1789-1868” in 2006.

Andrew Eric Taslitz was born in the Bronx. He was a 1978 graduate of Queens College in New York and a 1981 graduate of the University of Pennsylvania’s law school.

Earlier in his career, he was an assistant district attorney in Philadelphia and an associate of the Philadelphia law firm Schnader Harrison Segal & Lewis.

He was vice chairman of the governing council of the American Bar Association’s criminal justice section and a past chairman of the editorial board of Criminal Justice, a magazine produced by the association.

Survivors include his wife of 32 years, Patricia Sun of Reston; his father, Saul Taslitz of the Bronx; and a sister.
