IN March 1922 a ' Hyndman Memorial Committee' made its appearance, with an impressive membership including Lady St. Helier, the Countess of Warwick, Bernard Shaw, Sir James Frazer (the anthropologist), Wickham Steed ( editor of The Times), R. W. Seton-Watson, and Thomas Hardy, whose acquaintance Hyndman had made during the war. The Committee arranged for a bronze bust of Hyndman, the work of the young sculptor Edward Lacey, to be presented to the National Portrait Gallery; and it sponsored two Hyndman Memorial Lectures, on successive anniversaries of his birthday. The earlier of these, in 1923, was delivered by R. W. Seton-Watson, and his subject was 'The Emancipation of South-Eastern Europe'. A year later, F. J. Gould spoke on 'Hyndman as Prophet of Socialism'.
Meanwhile, Rosalind Travers Hyndman had been completing her last work of devotion for her husband--the memoir of the last decade of his life, published in 1923 under the title The Last Years of H. M. Hyndman. A few days after sending the manuscript to the publishers, she took an overdose of sleeping tablets and died on 7th April 1923. By her will all her possessions were to go to such causes as would keep alive the memory of her husband's work, except for £600 in cash, to be divided among needy members of the S.D.F. All pecuniary benefits from his or her literary works were to finance a 'Hyndman Literary Trust', for the publication or republication of works by or about Hyndman;
