Björn Rüther is a trainer of Hammaborg – Historischer Schwertkampf e.V. and leads the Meyer Class training group in Hamburg.
He started training HEMA in 2011 and quickly found his passion for the works of Joachim Meyer, based on which he has founded and trained a Meyer trainings group in 2014. Some time later he also started to publish videos on interpretations and insights on historical fencing based to the treatises of Meyer on his youtube channel. By November 2018, the 86 videos have collected nearly half a million clicks and have entertained (and hopefully helped) more than 6500 subscribers.
