Answer 2

Answer:

1844

Explanation:

His formal elementary schooling was limited and he taught himself using science books well enough to become a school teacher. He attended Marshall College[2] and despite financial difficulties, he was able to graduate from Bethany College's first graduating class in 1844. He would continue teaching in Missouri and Tennessee until 1858. At that point, he took up a full-time position on the staff of American Ephemeris and Nautical Almanac in Cambridge, Massachusetts.
