Hitler’s Moustache: Made in America

This I didn't know:

The [toothbrush moustache] was introduced in Germany in the late 19th century by visiting Americans.^[1] Prior to the toothbrush, the most popular style was called the Kaiser moustache, perfumed and turned up at the ends, as worn by the royalty in the German Empire and the German part of Austria.^[1][4] By 1907 enough Germans were wearing the new trimmed down and simple toothbrush moustache to elicit notice by The New York Times under the headline "'TOOTHBRUSH' MUSTACHE; German Women Resent Its Usurpation of the 'Kaiserbart'".
