Amos Kendall (August 16, 1789 - November 12, 1869) was an
American politician who served as U.S. Postmaster General under
Andrew Jackson and Martin Van Buren. Many historians regard Kendall
as the intellectual force behind Andrew Jackson's presidential
administration, and an influential figure in the transformation of
America from an agrarian republic to a capitalist democracy. In
1857, Kendall opened a school for deaf children, which later
expanded and became Gallaudet University for the deaf.
