US Naval Academy Class of 1892.

The United States Naval Academy opened in Annapolis, Maryland,
with 50 midshipmen students and seven professors. Known as
the Naval School until 1850, the curriculum included mathematics
and navigation, gunnery and steam, chemistry, English, natural philosophy, and French.

The Naval School officially became the U.S. Naval Academy in
1850, and a new curriculum went into effect, requiring midshipmen
to study at the academy for four years and to train aboard ships
each summer—the basic format that remains at the academy to
this day.
