Marquette's first high school was constructed in 1859 on property donated by Morgan Hewitt. Located at the corner of Pine and Ridge Streets, the community initially opposed the project, citing its remote location. Nevertheless, the red brick building with separate entrances for boys and girls was used until 1875, when it was demolished and replaced by a larger brownstone building in 1878. After fire claimed the brownstone in February 1900, the Howard High School (named after
John M. Longyear's son) was constructed in 1902 along with an elementary school and a manual training building. However, the school had been built to accommodate 200 students, but reached an enrollment of nearly 400 by 1915, so the community began a search for a new site. Harriet K. Adams, widow of pioneer Sidney Adams, donated land on the corner of Front and Hewitt streets for a new high school, and gave $2,500 for gymnasium equipment, but World War I postponed those plans until 1923. In 1925, voters approved a bond issue of $475,000 to build the new high school on the 8 lots on Front Street between Ohio Street and Hewitt Avenue (as well as expand the Fisher School).
Louis Kaufman donated $26,000 to the school board to replace the funds it had spent on land acquisition, so that more money could be spent on construction. In appreciation, the board voted unanimously to name the school after Kaufman's mother, Juliet Graveraet; they later named the auditorium after Kaufman himself. Graveraet High School was replaced in 1964 by the present structure at Fair and Lincoln avenues. In 2023, Marquette Area High School dropped the schools 'Redmen' nickname. In 2024, the school adopted the 'Sentinels' nickname. == Demographics ==
