Background:
In 1836 William Williams Mather was appointed geologist of the first district, or 21 counties, of New York State. This work required seven years, and his final report was a quarto of 671 pages, with forty-six colored plates, a great undertaking for the early days of geological research. From 1837 to 1840, he also superintended the geological survey of the state of Ohio, and made elaborate reports (2 vols., Columbus, 1838). In 1838/9 he made a report upon the geological reconnaissance of the state of Kentucky.

Mather, William W. 1804 - 1859
Mather was an important American geologist and natural historian. Mather was born in Brooklyn, Connecticut to an old New England family. In 1823, as a young man, he entered the West Point military academy after which he served as a 2nd Lieutenant in the Seventh Infantry. His interest in Chemistry and mineralogy soon called him back to West Point where he acted as an Assistant Professor of Geology. After resigning from the Army in 1834 with a rank of 1st Lieutenant, Mather accepted a position as Professor of Chemistry at the University of Louisiana. Later he was employed as Professor of Natural History and Sciences at the University of Ohio, was appointed Geologist of the First Geological District of New York for Governor William H. Seward, and was the State Geologist of both Ohio and Kentucky. In 1847 Mather became president of the University of Ohio. During his long career Mather made copious notes regarding his geological explorations, published profusely, and had a lively and extensive correspondence - much of which remains accessible to this day. Mather reports on one humorous incident in Long Island where, while collecting rock specimens, he had a run-in with a local farmer. The famer, observing the care with which Mather collected and cataloged his rock specimens, assumed that Mather had, in fact, discovered gold! Mather died in Columbus, Ohio on February 26, 1859. Today the W.W. Mather Medal is an important Geologic Reserach commendation. (Collections of the Minnesota Historical Society, p. 133.)

Endicott and Company (fl. c. 1828 - 1891) was a New York based family run lithography firm that flourished throughout the 19th century. The firm was founded by George and William Endicott, brothers who were born in Canton, Massachusetts. George Endicott (June 14, 1802 - 1848) trained as a lithographer under Pendleton Lithography from January of 1826. He later worked as superintendent of Senefelder Company until the summer of 1828. Afterwards, in 1830, he relocated to Baltimore and partnered with Moses Swett. Endicott and Swett relocated to New York City in December of 1831. They remained partners until July of 1834 when the relationship dissolved. George set up shop on his own account at 359 Broadway. William Endicott (1815 - 1851), George\\\'s younger brother of 14 years, joined the firm in 1840 and was made a partner in 1845, after which the name of the firm was changed to G. and W. Endicott. George Endicott died shortly afterward, in 1848, but William continued operating the firm as William Endicott and Co. until his own 1851 death at just 35 years. The firm was carried on by his widow Sara Munroe Endicott until it was taken over by her son, Francis Endicott, who ran the firm from 1852 to 1886. George Endicott, Jr. subsequently ran the firm from 1887 to 1891. Peters, in his important work on American lithography America on Stone writes \\\"it is hard to summarize the Endicotts. They did everything and did it well . . . [they] worked with and for Currier and Ives, yet in spite of all that much of their work lacks real individuality.\\\" The Endicott firm was responsible for many 19th century views and plans of New York City and state as well as plans of Sacramento, California, and the Midwest.
