Reitwiesner was born in Havre de Grace, Maryland on 8 March 1954 and grew up in Aberdeen, Maryland and Silver Spring. His grandfather was a board member of the National Genealogical Society and from the age of five, Reitwiesner would explore his grandfather's library.
After graduating from Montgomery Blair High School in 1972, Reitwiesner joined the Library of Congress's Congressional Research Service (CRS) as a cart pusher. He spent the rest of his working life in menial jobs at the Library of Congress so that he could devote his time pursuing his interest in genealogy. Although much of his work was self-published on the internet, he acquired a reputation for meticulousness and accuracy and many genealogists cited him in their publications.
He died of cancer in Washington DC on November 12, 2010.
