Answer:
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.
