Fred K. Fleagle

Fred K. Fleagle is the credited author of Social Problems in Puerto Rico, a work originally published in 1917 and preserved today in public-domain and book-catalog records. The book’s continued availability through digitized archives suggests that his main legacy is tied to that study rather than to a widely documented literary or public career.

Reliable biographical information about Fleagle himself appears to be very limited in the sources I could confirm during this search. I was able to verify the existence of his book and modern catalog listings for it, but I did not find a solid contemporary biography, major reference entry, or clearly documented portrait.

Because the record is so thin, the safest picture of him is as an early 20th-century author or researcher whose name survives chiefly through this publication. If more archival material surfaces, a fuller account of his life may become possible.
