Gertler began to sculpt in the autumn of 1916. He temporarily ceased painting, and on 13 September 1916 started a small plasticine model of 'Acrobats'. A few days later he made the two figures out of clay, using the small plasticine model as his guide. It is not known when this unique bronze cast was made. By November Gertler was making a carving of his painting 'Merry-Go-Round' but this does not seem to have survived. And in January he made a wood carving of 'Acrobats'. He wrote to his friend Richard Carline of his reasons for making sculpture: 'it is a natural and necessary development and it is real pleasure that makes me do it.'
