Input: Question: How many artists had won the gold medal from the Royal British Society of Sculptors before Montford did? Passage:Montford was president of the Victorian Artists Society 193032. His generally good work as president was occasionally marred by a certain lack of tact. Some of Montford's best work about this period included the bronzes, "Water Nymph" and "Peter Pan", now in the Queen Victoria Gardens, Melbourne, and "The Court Favourite" in the Flagstaff Gardens, Melbourne. Other work includes relief portraits of eight Australian statesmen in the King's Hall, Parliament House, Canberra, and the war memorial for the Australian Club, Sydney. He was greatly encouraged and pleased on learning in 1934, that his statue of Adam Lindsay Gordon at Melbourne had been awarded the gold medal of the Royal British Society of Sculptors for the best piece of sculpture of the year. Another excellent piece of work is his vigorous statue of John Wesley in front of Wesley Church, Melbourne. His George Higinbotham near the treasury is less successful. Other examples of Montford's work are the memorials to Carlo Catani (St Kilda), William Benjamin Chaffey (Mildura), Sir Ross Macpherson Smith (Adelaide), and 'Pioneer Women' (Sydney). Montford is represented in the National Gallery of Victoria in Melbourne by "Atalanta", the "Spirit of Anzac", and two busts, and he is also represented in the Art Gallery of South Australia in Adelaide. He provided a model from which a portrait bust of Socrates was carved for the University of Western Australia by Victor Wager in 1932.
