Designed in 1936 by Erich Mollowitz for C.E. Weber. This typeface was also published by J. D. Trennert as Rheingold. Stephenson Blake copied it as Mercury. The Brits altered a few characters that apparently were perceived as too Germanic, including the stemless ‘d’ and the ‘Z/z’ and ‘7’ with crossbars. Changes further affected ‘E’, ‘F’ and ‘M’. The metal Forelle came in two weights. Dieter Steffmann has digitized the bolder one and made it available as a free font.
