Task: Question Answering
Input (English): Passage: Fuller's time at Adyar was eventful. Leadbeater arrived around the same time as Fuller, and soon afterward he "discovered" the person he believed would become a global teacher and orator, Jiddu Krishnamurti (then in his teens). Leadbetter and others tutored Krishnamurti. Fuller may have taught him photography. She also had a small studio built in the grounds, and painted. Her works from the period include a portrait of Leadbeater and Portrait of the Lord Buddha. McFarlane emphasises the significance of the latter work, pointing out that it is "strikingly modern" in comparison to all of Fuller's other work, and more radical than compositions created by Grace Cossington Smith and Roland Wakelin, half a decade later. The painting owes much to theosophy's emphasis on seeing the subject "through a psychic, visionary experience".
Sources describing Fuller's movements after her time in India sometimes are ambiguous. She arrived in England in June 1911, where she marched with Besant in the suffragette protests associated with the coronation of George V. She continued to paint portraits, but found it difficult to realise the transformation in her art that she had conceptualised in India:I have painted a great many portraits since I have been in England, and have been, I suppose, fairly successful—though I have done nothing in any way remarkable. The hidden inner life has not yet succeeded in expressing itself on canvas, and I can only write myself as one who aspires to a greater art, but who has not yet achieved. 
Question: What is the last name of the person who found it difficult to realise the transformation in her art ?
Output (English): Fuller.
