Halbstarke ("beatnik", literally "half-strongs") is a German term describing a postwar-period subculture of adolescents – mostly male and of working class parents – that appeared in public in an aggressive and provocative way during the 1950s in Germany, Austria and Switzerland. Later, the term sometimes described youths in general. While in German, it is still in use today for young, aggressive, mostly male adolescents, it has mostly fallen out of active usage in English.
The word itself literally means “the half-strong”. Its origins can be traced back to a manufacturing technology named Walken (= to tumble/ mill/ full), via the word’s synonym Halbgewalkte– “half tumbleds”. Seen that way, the word is a defamation, because it can be associated with “unformed” and “premature” (in German, there also are a few other slight verbal slanders containing “halb”: e.g. halbgebildet (literally: half-educated) and halbe Portion (literally: half dish / half portion, used for children or adolescents that appear weak). But it is likely that the defamation was not as defamatory to the subculture itself, because its members began calling themselves “Halbstarke”, too. In German, both terms also have an adjective-form (halbstark / halbgewalkt).
These Halbstarken had found prototypes for their fashion and style in American movies, e.g. James Dean in Rebel Without a Cause (German title: …denn sie wissen nicht, was sie tun) and Marlon Brando, as well as the stars of rock 'n' roll, that was gaining popularity then. In 1956 Karin Baal and Horst Buchholz became idols thanks to the movie Die Halbstarken. That same year Bill Haley & His Comets' song Rock Around The Clock reached #1 in the German Pop charts. Often, the Halbstarken wore a quiff, jeans, checked shirts and leather jackets. Their look separated them from the other, more widespread, German youth culture. Mopeds and motorbikes were very popular and used for riding in 'gangs' (as seen in American movies). Because there weren't a lot of alternatives, the Halbstarken often spent their leisure time outdoors. Their cliques met at corners of the road, in parks or at other public places. This behaviour wasn’t appreciated by elder citizens and so they described it as “bumming around” (gammeln). Rock 'n' roll offered tunes and rhythms that were revolutionary and a catalyzer for the youths' emotions and fears, unlike the then-popular but shallow genre Schlager. The effect of this was probably maximized by the new music being rejected by wide parts of the population. During the 1950s, more or less 5% of youth could be referred to as Halbstarke.
