Wolfgang Linschmann is the last glass blower of the firm Otto Pressler, which was a company that made Geissler and Crookes tubes during Tesla's time (even Tesla tubes). He is in his 80s and still making tubes even with many physical ailments. An amazing man indeed! He describes Otto Pressler testing each X-Ray tube with his own hand...something that killed nearly all early glassblowers...
