Vincent F. Seyfried (April 18, 1918-April 14, 2012, aged 93) was an American historian of Long Island. His work between 1950 and 2010 includes eleven books on trolley systems in Queens and Long Island, twelve books on areas of Queens, a seven-volume set on the Long Island Rail Road, and a history of the founding of Garden City, where he was Village Historian from 1987 to 2006. He provided many entries on Queens history for The Encyclopedia of New York City (1995).
Seyfried was born in Ridgewood, (Queens, New York City) NY on April 18, 1918 and as a child lived in Hollis. After receiving bachelor's and master's degrees in Classics from Fordham University in 1941, he was inducted into the Army in October 1941. After first being assigned for defense of the Panama Canal, in 1943 he qualified as a navigator in the Air Force. He flew 50 missions for the 15th Air Force based in southern Italy and was discharged 1945. Again living in Hollis, he started civilian life as an English teacher, finally working at Martin Van Buren High School in Queens Village until his retirement in 1979. He married Constance Goldsmith in 1955, and in 1960 they moved 10 miles east to Garden City, in Nassau County.
During his teaching career he spent his summer time researching an early interest in the trolley systems of Queens, which were being phased out in the late 1940s, and then historic parts of the Queens communities themselves. From his home in Garden City his interests expanded to the Long Island Rail Road, for which he provided a definitive history from its founding until 1919, and the trolley lines that ran on Long Island in the early 1900s. For the centenary of the Village of Garden City in 1969 he provided a book on its founding in 1869 until the formation of the Garden City Company in 1893.
Seyfried was a frequent contributor to the activities of the Greater Astoria Historical Society in Queens, where a room is named in honor of his efforts. He also spent many hours at the Shore Line Trolley Museum in East Haven, Connecticut helping restore their rolling stock. He was a founding trustee of the Garden City Historical Society.
After his wife died in 1985 (they had no children) he continued his publishing until, in declining health, he moved from Garden City to assisted living facilities. He died at age 93 on 14 April 2012 and was interred at St. John's Cemetery, Middle Village (Queens).
