It's an anniversary issue for the Jewish daily Forward, founded in 1897. Here's a piece for the occasion on how the paper got its name. I hope the basic story is accurate, because there are egregious mistakes of detail. Wilhelm Liebknecht wasn't murdered in 1919 together with Rosa Luxemburg. It would have been difficult, as he died in 1900. It was his son Karl who was murdered in 1919. The author of the article also credits Forward's founder, Abraham Cahan, with remarkable powers of historical foresight:
[W]hen Cahan founded the Yiddish Forverts in 1897, the German Vorwärts was a going concern. Presumably he wanted the name, despite its shopworn character, precisely because it was well known in radical Jewish circles and was a way of declaring where the Forverts intended to stand politically - namely, in the 19th-century social-democratic tradition and in favor of revolution but against the Leninist "dictatorship of the proletariat."In 1897 Cahan could not have had any idea of a specifically Leninist version of this idea, as Lenin hadn't yet written the works that were to lay out distinctively 'Leninist' political positions.
