Between about 1906 and 1911 there was a ferro concrete expert in Auckland New Zealand called Charles Rosegger. He had been arrested in Poland and sent with fellow students to Siberia where a party of 12 intially escaped. Only five survived an encounter with a Russian Patrol but after a 3000 mile trek across the Gobi Desert they made it to China. [refer PapersPast website] From Singapore Rosegger spent 7 years in America before coming to Auckland where he taught engineering. After working on Grafton Bridge he moved to Sydney and apartentlly died in Gosford in 1919. His education in ferro-concrete design must have been from America.
