Henry Simmons Frieze (September 15, 1817, in Boston – December 7, 1889) was an American educator and academic administrator.

[1] One of his students at the grammar school was James Burrill Angell, whose career would later become closely associated with Frieze's at the University of Michigan.

The resolution passed when it was reintroduced in 1870, and the first woman enrolled that same year,[5] though, at least in the opinion of James Angell, Frieze was not so much a champion of the policy change as he was acquiescent to the wishes of the regents where his predecessor had been vocally opposed.

[6] He also introduced the "diploma system," whereby students who graduated from college preparatory programs at Michigan high schools that had been accredited by the Board of Regents could enroll at the university without examination.

[8] Henry Frieze died on December 7, 1889, in Ann Arbor and is buried at Forest Hill Cemetery.
