The most famous hanger, and possibly the first one, was made of wire. However, before wire hangers, hooks were used for hanging coats.
One morning in 1903, Albert J. Parkhouse arrived at his workplace, the Timberlake Wire and Novelty Company, a company in Jackson, Michigan, which manufactured various products made from wire. He looked for a hook to hang up his hat and coat, but there was none available.
Terribly annoyed, Parkhouse grabbed a piece of wire, folded it into 2 large elongated semicircle wreaths, one opposite the other, and turned both ends towards the center to create a hook. Then, he simply hang his coat and went to work!
Three years later, Elmer D. Rogers created a hanger, also using a paper tube at the bottom bar of the hanger, for hanging trousers. This type of hanger is still used nowadays.
