A cache of beautiful nineteenth-century German scientific devices that has survived many misfortunes now needs a new home, reports Alison Abbott.

The ingenious 1847 'Multiplikator' was the finest instrument of Emil du Bois-Reymond (1818–96), the first scientist to measure current flowing in nerves and muscles in the working human body. Built in Germany, in collaboration with instrument-maker Johann Georg Halske, the device's sleek, high-precision form presages the Bauhaus aesthetic of eight decades later.
