Franz Melde

Standing waves were first discovered by Melde, who coined the term "standing wave" (stehende Welle) around 1860. What is known as "Melde's experiment", "a lecture-room standby", demonstrates standing waves and their patterns on a string, is used to measure the speed of transverse wave, and to determine the effect of tension, length, and mass on the transverse waves of a string. In 1859 Melde generated parametric oscillations in a string by employing a tuning fork to periodically vary the tension at twice the resonance frequency of the monochord string.

He was a member of the Landsmannschaft fraternity. In 1885 he was elected to the Academy of Sciences Leopoldina and in 1893 received a silver medal at the Chicago Columbian Exposition.
