What is the answer for the question: What is the last name of the person who left his skeleton in his will for the Grainger Museum? from the following article ?  By 1957 Grainger's physical health had markedly declined, as had his powers of concentration. Nevertheless, he continued to  visit Britain regularly; in May of that year he made his only television appearance, in a BBC "Concert Hour" programme when  he played "Handel in the Strand" on the piano. Back home, after  further surgery  he recovered sufficiently to undertake a modest winter concerts season. On his 1958 visit to England he met Benjamin Britten, the two having previously maintained a mutually complimentary correspondence. He agreed to visit Britten's Aldeburgh Festival in 1959, but was prevented by illness. Sensing that death was drawing near, he made a new will, bequeathing his skeleton "for preservation and possible display in the Grainger Museum". This wish was not carried out.Through the winter of 1959–60 Grainger continued to perform his own music, often covering long distances by bus or train; he would not travel by air. On 29 April 1960 he gave his last public concert, at Dartmouth College in Hanover, New Hampshire, although by now his illness was affecting his concentration. On this occasion his morning recital  went well, but his conducting in the afternoon  was, in his own words, "a fiasco".  Subsequently confined to his home, he continued to revise his music and arrange that of others; in August he informed Elsie  that he was working on an adaptation of one of Cyril Scott's early songs.  His last letters, written from hospital in December 1960 and January 1961, record  attempts to work, despite failing eyesight and hallucinations: "I have been trying to write score for several days. But I have not succeeded yet."Grainger died in the White Plains hospital on 20 February 1961, at the age of 78. His body was flown to Adelaide where, on 2 March, he was buried in the Aldridge family vault in the West Terrace Cemetery, alongside Rose's ashes. Ella survived him by 18 years; in 1972, aged 83, she married a young archivist, Stewart Manville. She died at White Plains on 17 July 1979.
The answer to this question is:
Grainger
