Berthold Schwarz

Berthold Schwarz (sometimes spelled Schwartz), also known as Berthold the Black and der Schwartzer, was a legendary German (or in some accounts Danish or Greek) alchemist of the late 14th century, credited with the invention of gunpowder by 15th- through 19th-century European literature.

The purported period of Schwarz' activity (late 14th century) thus falls between the first reports of gunpowder in Europe (late 13th century) and the development of effective applications in artillery (mid 15th century).

It is unclear whether Schwarz is a historical person. It has been suggested that he was a historical alchemist who had developed gunpowder in Germany, but other scholars consider him purely legendary.(Partington, 1960)

Schwarz is possibly identical with Bertold von Lützelstetten, a scholar who is recorded as "magister artium Bertoldus" at the University of Paris during 1329-1336.

Other sources identify him with one Konstantin Angeleisen or Anklitzen who was persecuted for being an alchemist and had to flee to Prague, where he was executed in 1388.

It is also possible that Schwarz is not a historical person at all, but a symbolic inventor figure taking his name from that of Schwarzpulver "black powder", the German term for gunpowder (Gartz 2007).

The first reference to Schwarz is found in an anonymous manual of pyrotechnics of ca. 1410, preserved in various 15th century copies. The relevant passage credits an alchemist and master of arts "Master Berthold" (maister perchtold) with the accidental discovery of gunpowder, without giving any further details as to time or place.

Such details are first reported by Franz Helm, an author active in Landshut during the 1520s to 1530s, who is also the first to introduce the epithet "the Black" (in Latinized form, as niger). According to Helm,

Feldhaus (1910) thinks that reports of a "Master Berthold" in the early 15th century, barely 25 years after this master's death, should be taken seriously as historical testimony of an alchemist Berthold, called "the Black", member of the Order of St. Bernhard, who developed a recipe for effective gunpowder in ca. 1380, and who was possibly executed as a magician some years later. The recipes given in the 15th-century German manuals for pyrotechnics would then be directly derived from the recipe as developed by Berthold.
