Walter Minder (August 6. 1905–April 4.1992) was a Swiss mineralogist and chemist.[1] He together with Alice Leigh-Smith announced the discovery of element 85 (now called astatine)[2] in 1940[3] and 1942.[4] He proposed the name helvetium in 1940[3] and anglohelvetium[4] in 1942 for the new element. Later it was proven that in fact he had not discovered element 85.[2][5]
