Eliot arranged for a formal separation
                 February 1933, and thereafter
                 shunned her entirely,                            hiding from her
                and instructing            his friends – including members of the Bloomsbury Group [Virginia Wolfe's &
  sometimes    Joyce's crowd]               and  the publisher Faber & Faber,
               where he was a director –             not to tell her where he was;
                 Her brother had her              committed to an asylum in 1938,
                                   after she was found
                     wandering                the streets of London
                       at five               |              in the morning,
                     asking whether Eliot had been beheaded:
                    Apart from one escape attempt
she remained there                      until she died nine years
later at 58;                  said to have suffered a heart attack,     there is suspicion of                 suicide                by deliberate drug overdose;
Eliot                  winning the Nobel                       Prize for Literature
                                                      ­                          the following year;

Carole        Seymour-Jones writes that it
was out of the turmoil & tumultuous ***        
                                        of the marriage
                  [in which Vivian would cry out in agony;
                        due to untreated cysts that caused  horrendously painful  cramps & unstoppable       bleeding];          
that Eliot   produced The Waste Land,
one                         of the 20th century's
         finest love poems to the horrors of the             Abyss [seen & read
         as
         personifying the whole of the 20th century];
        Eliot's sister-in-law, Theresa,
        said of the relationship:
        "Vivienne ruined Tom as a man,        but she made him a poet."
