E.B. Smith, a retired University of Maryland history professor, died of congestive heart failure at the Hospice of the Chesapeake in Harwood on April 30, the day before his 93rd birthday. He lived at Tracys Landing on the western shore of the Chesapeake Bay.

A daughter-in-law, Barbara Smith, confirmed his death.

Dr. Smith joined the faculty at Maryland in 1968 and became a professor emeritus in 1990. He specialized in the Civil War and had written about the pre-Civil War presidencies of Zachary Taylor, Millard Fillmore and William Buchanan and about the Civil War-era politician Francis Preston Blair, a founder of Silver Spring.

Dr. Smith was a Fulbright professor at universities in Japan and Russia and was an exchange professor at the University of Beijing. Before joining the Maryland faculty, Dr. Smith taught at Youngstown University, Iowa State University and the University of Wisconsin.

Dr. Smith ran unsuccessfully for the U.S. Senate as a Democrat in Iowa in 1962 and 1966. He served on the U.S. Board of Foreign Scholarships, which administers the Fulbright program.

His wife of 58 years, Jean Smith, whose maiden name was also Smith, died in 2002.
