    According to Chauvenet
    (vol. 1, p. 131) the mathematical law of atmospheric
    refraction is due to Bessel
    (who was a student of Gauss, and consequently lived
    in the beginning of XIX century).

    P.S. I've seen online (Google books or Abebooks,
    something like that)
    that there is a new cheap reprint of Chauvenet.
    It was out of print few years ago but Dover
    edition was always available for moderate price.
