Coolidge began investigating how he might improve tungsten lamps by making a bendable or "ductile" wire. In 1909 he came up with the answer. By putting an ingot of sintered tungsten through a series of hot swagings and drawings through successively smaller dies, bendable wire of many diameters could be made.
