You can see Edward Shorter's historical perspective on "chronic fatigue" (circa 1993) in an article beginning on page 6 of a compendium entitled "Chronic Fatigue Syndrome."

The book appears to be the proceedings of a symposium on Chronic Fatigue Syndrome held at the CIBA Foundation in London, 1993.
The first portion of Shorter's article is a review of the rise of the diagnosis of neurasthenia (not the later "neur
omyasthenia") in the second half of the 19th century. He mentions how, after 1880, the disease was sometimes treated with early forms of surgery, apparently producing placebo effects in some. By WWI, however, instances of so-called "bed cases" of the ailment had become quite rare. Citing concerns that neurasthenia was a 19th century "wastebasket" diagnosis, Shorter concludes, "It is thus evident that great caution is indicated before assuming an even rough equivalence between neurasthenia and chronic fatigue."
The second portion of the article is largely a distillation of a brief subchapter in his 1992 book, "From Paralysis to Fatigue" entitled
The Epidemic of Chronic Fatigue (p. 307-314). It goes over some 20th century forerunners of the chronic fatigue syndrome.
In both the book and article, Shorter argues that the epidemic of "chronic fatigue" had its origins in four different diagnoses: neuromyasthenia (Los Angeles, 1934), Epstein-Barr Virus (following its link to mononucleosis in 1968), myalgic encephalomyelitis (Royal Free Hospital, 1955) and fibromyalgia (first called "fibrositis" in 1904).
In "From Paralysis to Fatigue," he says:
"These various diagnoses then were appropriated by individuals with psychosomatic illness who wished to confer the imputed organicity of the diagnosis on their own condition. These organic diagnoses represented templates on which patients suffering from a wide variety of nonspecific symptoms could model their complaints as they brought them to the doctor."
Edward Shorter, From Paralysis to Fatigue (New York:The Free Press, 1992), p. 307
However in his symposium article of the following year (which may have been given as a speech before an audience of both the organic and psychosomatic camps) he was seemingly more circumspect:
"In sum, it is not the role of a historian to determine whether the current epidemic of attributing such symptoms as pain and weariness to chronic fatigue syndrome is the result of epidemically spreading organic disease, or of a psychic epidemic."
But he then quotes others who warn that there is "a market for somatic labels" among "stressed out or somaticizing patients," and that "the essence of somatization is that its victims take their symptoms, psychogenic in nature, to be evidence or organic disease."
He ends by cautioning physicians not let their empathy lead them into a blind alley.
Of course, his views may have changed over time.
Despite his avowal of humility in regard to drawing scientific conclusions in 1993, apparently he was not so deferential after the late 1990's, when, according to Shorter (just five years or so after the CIBA symposium),
"...it became apparent to the patients that nobody believed they had a distinct organic disease, as real as mumps, called “CFS."

Nothing has changed since then in scientific terms. There have been no convincing new studies, no breakthrough findings of organicity, nothing.
And there never will be."
