William W. Mather (May 24, 1804 - February 26, 1859) 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. (<i>Collections of the Minnesota Historical Society</i>, p. 133.)
