Career and family life
He was born and raised in Baltimore, Maryland. Some of his books said that he was born in Norfolk, Virginia although he later claimed that was a mistake; he attended high school at the Baltimore City College. Chalker earned a BA degree in English from Towson University in Towson, Maryland, where he was a theater critic for the school newspaper, The Towerlight. During 2003, Towson University named Chalker their Liberal Arts Alumnus of the Year. He received a Master of Arts in Liberal Studies from Johns Hopkins University in Baltimore.
Chalker intended to become a lawyer, but financial problems caused him to become a teacher instead. He taught history and geography in the Baltimore City Public Schools from 1966 to 1978, most notably at Baltimore City College and the now defunct Southwest Senior High School. Chalker lectured on science fiction and technology at the Smithsonian Institution in Washington, D.C., the National Institutes of Health in Bethesda, Maryland, and numerous universities.
Chalker was married in 1978 and had two children, David, a game designer, and Steven (later Samantha), a computer security consultant.
Chalker's hobbies included esoteric audio, travel, and working on science-fiction convention committees. He also had a great interest in ferryboats; at his fiancee's suggestion, their marriage was performed on the Roaring Bull boat, part of the Millersburg Ferry, in the middle of the Susquehanna River in Pennsylvania.
