Helvetium was the suggested name of chemical element number 85, now known as astatine, given to it by the Swiss chemist Walter Minder. Walter Minder announced the discovery in 1940.[1] He chose the name based on "Helvetia", the Latin name for Switzerland, to honor his country of birth.

In the year 1942 he together with Alice Leigh-Smith announced a second time the discovery of element number 85.[2] This time he proposed the name anglohelvetium to honor also England, the home of Alice Leigh-Smith.

Later it was proven that in fact he had not discovered element 85.[3][4][further explanation needed]
