Thomas Fitz Hugh was born of colonial Virginia stock and after a decade's sojourn in Austin, TX, returned to his old school as the hand-picked successor of Col. William E. Peters. In Charlottesville, he devoted himself to his accentual theory of Latin metrics, a theory he ingrained in his students and first published in 1909, but which he recanted late in his life. He edited the letters of his predecessor George Long and those on classical subjects by Thomas Jefferson.
PUBLICATIONS: The Philosophy of the Humanities (Chicago, 1897); The Outlines of a System of Classical Pedagogy (Berlin, 1900); The Sacred Tripudium, the Accentual and Rhythmic Norm of Italico-Romanic Speech and Verse (Charlottesville, 1909); The Literary Saturnian, the Stichic Norm of Italico-Keltic, Romanic, and Modern Rhythm (Charlottesville, 1910); Indoeuropean Rhythm (Charlottesville, 1912); The Letters of George Long (Charlottesville, 1917); The Letters of Thomas Jefferson Concerning Philology and the Classics (Charlottesville, 1918).
Although I'm unqualified to judge, Fitz Hugh (also spelled FitzHugh or Fitz-Hugh) seems to have been a bit of a crank, ignored or mocked by other scholars for his heterodox metrical theories. Most of his publications appeared in the Bulletin of the School of Latin, University of Virginia (Charlottesville). I've compiled the following list, but I haven't seen some of the publications, and I can't guarantee the completeness or accuracy of the list:

A few other publications by Fitz Hugh not published in the Bulletin of the School of Latin:
- "The Latin Accent," Glotta 8 (1917) 241-243
- "Latin Rhythm," Glotta 8 (1917) 243-246
- "Latin Metric," Glotta 8 (1917) 247-248
- The Pyrrhic Accent and Rhythm of Latin and Keltic (1923), rev. J. Fraser, Journal of Roman Studies 12 (1922) 313, Journal of Hellenic Studies 43 (1923) 214, and Classical Review 38 (1924) 45
The "J. Fraser" who unfavorably reviewed a couple of Fitz Hugh's works was (I think) John Fraser (1882-1945), Professor of Celtic, Jesus College, Oxford, from 1921 until his death. Here is an excerpt from one of Fraser's reviews (Classical Review
38  45):
[T]he details of Professor Fitzhugh's
theory have really nothing to support them.
The introduction into the argument of the
hypothesis of an Italo-Celtic unity involving
common principles of metre appears to be based
on a misunderstanding of the terminology of
linguistic science. The examples of Irish
verse which Professor Fitzhugh produces to
illustrate the theory merely prove that he should
carefully avoid the subject.
