In 1942, Leigh-Smith and a Swiss chemist, Walter Minder jointly announced the discovery of element 85 (now called astatine)[4] in 1942.[5] They proposed the name anglohelvetium for the new element, in order to honor both of their home countries- "anglo" for Leigh-Smith's England and "Helvetia" after the personification of Minder's country- Switzerland.[5] This was Minder's second attempt at discovering the element.
