Charles Conrad Abbott (June 4, 1843 – July 27, 1919) was an American archaeologist and naturalist, born at Trenton, New Jersey. He studied medicine at the University of Pennsylvania, and served as a surgeon in the Union Army during the Civil War. From 1876 to 1889 he was assistant curator of the Peabody Museum in Cambridge, Mass., to which he presented a collection of 20,000 archæological specimens; he freely gave also to other archæological collections. His book Primitive Industry (1881) detailed the evidences of the presence of pre-glacial man in the Delaware valley, and is a valuable contribution to American archæology. He was well known as a frequent contributor to the American Naturalist, Science, Nature, Science-News, and Popular Science Monthly. He also published many books on outdoor observation, such as A Naturalist's Rambles about Home (1884).
