1875 Bradley Geological Map of the Eastern United States and Canada

Frank Howe Bradley (September 20, 1838 - March 27, 1879) was an American geologist. Born in New Haven, Connecticut, Bradley attended that city's General Russell's Collegiate and Commercial Institute. He went on to matriculate at Yale College, graduating in 1863. While at Yale, he worked as part-time teacher at General Russell's school. After graduating he taught in Hartford, Connecticut for a year before enrolling as a student in the Chemical Laboratory of the Sheffield Scientific School in 1864-65. He traveled to the Isthmus of Darien during the summer of 1865 and while there he amassed large collections of corals and other zoological specimens, part of which was for the Yale Museum. He worked as an assistant geologist in the Illinois survey in 1867 and 1868 before becoming Professor of Natural Sciences at Hanover College in Hanover, Indiana. Then, in September 1869, Bradley left Hanover College to accept the Professorship of Mineralogy and Geology at East Tennessee University in Knoxville. He left East Tennessee University in 1875 and began developing a gold mine in northern Georgia, where he died when the bank of earth he was working under caved in. Apparently at the time of his death Bradley was 'operating one of the largest and best gold mills in [Georgia]'. Bradley married Sarah M. Bolles, on July 15, 1867, with whom he had four children. His wife and one daughter survived him. Two of his children died before him and one, an infant daughter, died on the same day as Bradley. More by this mapmaker...

Lemuel Swift Punderson (18?? – c. 1903) was a New York City and New Haven, Connecticut, based engraver, author, and publisher. The earliest records suggest Punderson worked in New York from about 1850 to 1855. In 1855 he relocated to New Haven, Connecticut, where he established his own engraving business. A map of New Haven by Punderson dating to 1852, suggest that he had close ties to New Haven even before he relocated there. In 1860 he partnered with Emil Crisand to found Punderson and Crisand, Engravers, Lithographers, and Printers. Punderson also had an interest in antiquities and co-authored the book History of the Antiquities of new Haven, published in 1870. His manuscripts are currently held by the Serling Memorial Library, Yale University, as the 'Lemuel Swift Punderson Papers.' Learn More...
