The Storm Glass was first invented in the mid-1700s and soon made it's way into ships and harbors around Europe to help give warning of approaching bad weather. It gained the most fame through Admiral FitzRoy who used a Storm Glass on the voyage in which he and Darwin traveled to the Galápagos Islands. As such, the instrument is sometimes called a 'FitzRoy Storm Glass'.
