Handwritten first page, German first page, English translation of (Röntgen 1895) from (Glasser 1958). Reproductions of reprint front covers from (Mould 1993).

Mould (Mould 1993) writes:”The paper cover of the first print run of his communication included the headline caption ‘Professor Röntgen’s wichtige Entdeckung!’ (Important Discovery by Professor Röntgen!), a caption with which he disagreed and thus caused the cover to be reprinted without the offending headline. The original copy (left) is probably the only one remaining and is now kept under lock and key in a safe in Würzburg.”
