Ethel Rosalie Harraden (Mrs. Frank Glover) (b. 1857 d. 1917) was an English pianist, composer and music critic. She was born in Islington, Middlesex, England, in 1857, the daughter of Samuel Harraden, a London/Calcutta agent, and studied at the Royal Academy of Music.
http://www.essaylet.com/author/beatrice-harraden/beatrice-harraden-biography.htmltells us that Samuel's youngest daughter, Beatrice, was born in Hampstead, London in 1864, and that her father, Samuel was "an importer of musical instruments" (hence, presumably, the connection with the registered design for a glass piano insulator). "Beatrice Harraden, though little known today, published novels and short-story collections between 1891 and 1928. She was an important early feminist novelist; she was also extremely active in the suffragette movement, which she describes in her book Our Warrior Women (1916). A founder of the Women's Social and Political Union (WSPU), formed in 1903, she travelled extensively on the Continent and in the United States; her hope was to facilitate international comity among women's groups."
In 1868, Samuel Harraden was living in St John's Wood Park. In 1891, he was head of household living at 5 Cannon Place, London (with previous addresses at 30 Lancaster Road and 34 Parliament Hill Road). Occupation given as East India Agent.
Samuel died in Hampstead, London in 1897.
