Allegorical bits of history in the "Hotel Infinity" story:


Set theory and the notions of cardinality were first developed by Georg Cantor in the late 1800's. 

Leopold Kronecker, another mathematician and a contemporary of Cantor’s, felt that the only mathematical concepts with validity were those whose construction could be described in a step-by-step manner - using only a finite number of steps. He was virulently opposed to Cantor’s notions of infinity, calling them "meaningless."  Kronecker tried to prevent the influential Crelle’s Journal from publishing Cantor’s work and for a time succeeded. If history is a judge, it has vindicated Cantor.

Cantor struggled with depression for much of his life, spent time hospitalized, somewhat like the breakdown in the story, and died in a sanatorium in 1918.

David Hilbert, perhaps one of the greatest mathematicians in the early 20th century, praising Cantor’s development of set theory, proclaimed “No one will drive us [mathematicians] from the paradise which Cantor created for us.” In a 1920’s lecture, Hilbert described a “Grand Hotel” with infinitely many rooms; the anecdote is remembered to this day as “Hilbert’s Hotel.” The anecdote was far shorter than the story I've assigned, which was written in 1991.
