 Following the death of his first wife in 1935 , Clark moved from Hawthorn to Ferntree Gully in Melbourne . A couple of years later in 1939 , he married his second wife , Phyllis Marjorie Claringbull , at the Office of the Government Statist , bearing two more daughters . Claringbull committed suicide in 1943 , three months after she gave birth to her second daughter ; Clark would later send them to an orphanage as he was unable to look after them . Clark 's intemperate attitude to his peers and superiors and lack of qualifications bedevilled his career , although he was welcoming to amateurs . In 1944 , Clark resigned from the National Museum of Victoria after Australian botanist Richard Pescott became the director of the museum . As a result , he moved to Mooroolbark and lived in poverty , losing all of his entitlements . Due to his reputable view as an authority on ants , Clark worked on a monograph of ants in Australia , supported by the Commonwealth Scientific and Industrial Research Organisation through grants . His first volume was published in 1951 , which covered the Australian bulldog ants ( subfamily Myrmeciinae ) . However , the first volume received poor reviews , and no further volume was released . In fact , it is unknown whether or not any further volume will be released .
