The “Crescent Camp” was a laboratory of sorts, where members of the “Royal Prussian Phonographic Commission” undertook cultural comparisons. In addition to linguistic and musicological recordings, body measurements were also taken on the prisoners under the direction of the anthropologist Felix von Luschan. The drawings that the German-Jewish painter Hermann Struck made on von Luschan’s behalf, however, were less concerned with the anthropological determination of “human types” than with the search for individual expression. Some of those portrayed put their names on the sheet.
