Carlton D. "Buck" Weaver was born in Grantsville, West Virginia, in 1921. Graduating from The Citadel in 1939, he entered Marshall College (now Marshall University) in Huntington, West Virginia that same year. Following his service as a dive bomber pilot in WWII, Weaver returned to school at West Virginia University, graduating with a degree in Petroleum Engineering in 1948. He worked for Ashland Oil, Inc. for 30 years.
His ancestors were among the first to move into the land that later became West Virginia, emigrating from Pennsylvania, after emigrating from Germany. He became fascinated with the land on which his ancestors lived and traveled. He had a love of maps and so began devoting his spare time to collecting maps of the TransAllegheny region. Weaver’s collecting took him to map dealers throughout the United States, as well as London. He took great pride in his ancestors and the land they occupied as depicted in the early North American maps he collected. In 1992 he donated “The Carlton D. Weaver TransAllegheny Map Collection” to Marshall University, where it is currently housed in the Archives and Special Collections Department in Morrow Library.
