  # Principal of Temple Grove Ladies' Seminary (Saratoga Springs, NY).
  # His pamphlet "A System of National Time for Railroads" (1870)
  # was the result of his proposals at the Convention of Railroad Trunk Lines
  # in New York City (1869-10).  His 1870 proposal was based on Washington, DC,
  # but in 1872-05 he moved the proposed origin to Greenwich.
! # His proposal was adopted by the railroads on 1883-11-18 at 12:00,
! # and the most of the country soon followed suit.
  
  # From Paul Eggert (2005-04-16):
  # That 1883 transition occurred at 12:00 new time, not at 12:00 old time.

! # From Paul Eggert (2016-09-21):
! # Dowd's proposal left many details unresolved, such as where to draw
! # lines between time zones.  The key individual who made time zones
! # work in the US was William Frederick Allen - railway engineer,
! # managing editor of the Travelers' Guide, and secretary of the
! # General Time Convention, a railway standardization group.  Allen
! # spent months in dialogs with scientific and railway leaders,
! # developed a workable plan to institute time zones, and presented it
! # to the General Time Convention on 1883-04-11, saying that his plan
! # meant "local time would be practically abolished" - a plus for
! # railway scheduling.  By the next convention on 1883-10-11 nearly all
! # railroads had agreed and it took effect on 1883-11-18 at 12:00.
! # That Sunday was called the "day of two noons", as the eastern parts
! # of the new zones observed noon twice.  Allen witnessed the
! # transition in New York City, writing:
! #
! #   I heard the bells of St. Paul's strike on the old time.  Four
! #   minutes later, obedient to the electrical signal from the Naval
! #   Observatory ... the time-ball made its rapid descent, the chimes
! #   of old Trinity rang twelve measured strokes, and local time was
! #   abandoned, probably forever.
! #
! # Most of the US soon followed suit.  See:
