Mount attended
Columbia College, graduating with an A.B. degree in 1834 (alongside
James William Beekman and
Isaac C. Delaplaine) and an A.M. degree in 1837. After graduating from Columbia, Mount
passed the bar and began practicing law after entering the law office founded by
James Alexander, the 4th
New Jersey Attorney General (who also served as attorney general for the
Province of New York and was the father of
William Alexander, Lord Stirling). Reportedly, Mount earned a fortune from practicing law, retiring after his father's death (after inheriting an "ample fortune") and four years before his own death in 1876. Mount also served as Assistant Secretary of the organization from 1851 to 1857, Secretary from 1859 to 1864, Fourth Vice-president from 1865 to 1866, Third Vice-president in 1867, Second Vice-president from 1868 to 1869, and First Vice-president in 1870. ==Personal life==
